Secure Spread Spectrum Communication System

View page
US Patent:
42414474, Dec 23, 1980
Filed:
Jul 22, 1969
Appl. No.:
4/843689
Inventors:
Marvin A. Epstein - Monsey NY
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H04K 100
H04K 300
US Classification:
375 1
Abstract:
A communication system is protected against jamming by modifying a conventional spread spectrum communication system by inserting errors, in the form of digital noise, into the pseudo-noise digital code used to generate the spread spectrum carrier. A bidirectional system is provided so that when jamming occurs, as a consequence of breaking the corrupted spread spectrum code, the pseudo-noise digital code and/or the percent of errors is changed in a prearranged manner to compensate for the jamming and/or reduce the likelihood of breaking the corrupted spread spectrum code. A conventional correlation receiver is employed to recover the intelligence.

Assignee:
ITT Manufacturing Enterprises - Wilmington DE
International Classification:

Digital Waveform Generator

View page
US Patent:
39834956, Sep 28, 1976
Filed:
Sep 29, 1975
Appl. No.:
5/617545
Inventors:
Marvin Aaron Epstein - Monsey NY
Assignee:
International Telephone and Telegraph Corporation - Nutley NJ
International Classification:
H03K 508
H03K 304
H03K 112
US Classification:
328 34
Abstract:
This generator generates COS(w. sub. o + w. sub. m)t, SIN(w. sub. o + w. sub. m)t, COS(w. sub. o - w. sub. m)t and SIN(w. sub. o - w. sub. m)t square wave waveforms. This is accomplished by inserting into a carrier square wave clock pulse stream one pulse with the cooperation of a modulation square wave clock in a first signal channel and by deleting from the carrier square wave clock pulse stream one pulse with the cooperation of the modulation square wave clock in a second signal channel. The resultant pulse stream in the first signal channel is suitably divided in a first binary divider and then further divided by a factor of two in a second binary divider to generate the COS(w. sub. o + w. sub. m)t waveform. The complement of the output waveform of the first binary divider is further divided by a factor of two in a third binary divider to generate the SIN(w. sub. o + w. sub.

Msk Digital Data Synchronization Detector

View page
US Patent:
40284905, Jun 7, 1977
Filed:
Nov 14, 1975
Appl. No.:
5/632044
Inventors:
Marvin Aaron Epstein - Monsey NY
Assignee:
International Telephone and Telegraph Corporation - Nutley NJ
International Classification:
H04L 1716
H04L 700
US Classification:
178 88
Abstract:
Baudot code characters each having start and stop bits are transmitted in the form of a MSK digital data signal having a stop-start triangle corresponding to adjacent stop and start bits of two adjacent Baudot characters. The MSK signal is correlated with MSK correlation waveforms to produce first and second correlation signals. Each of the first and second correlation signals are coupled to a different one of two delay lines each having three output taps separated by one bit time. The output signals from the output taps at a given time are appropriately summed to provide inphase and quadrature triangle signals. These triangle signals are operated on by an arithmetic unit to calculate many time and phase conditions of the MSK signal at one time and to produce third, fourth and fifth correlation signals as a function of assumed bit times. These third, fourth and fifth correlation signals are operated on by a ratio calculator to produce a ratio signal proportional to the ratio of a minimum magnitude squared to a maximum magnitude squared for all carrier phase angles for each of the assumed bit times. A synchronization detected signal is produced when the ratio signal value is less than a given amplitude threshold.

Filed:

Appl. No.:
5/628710
Inventors:
Marvin Aaron Epstein - Monsey NY
Assignee:
International Telephone and Telegraph Corporation - Nutley NJ
International Classification:

These first and second correlation signals are operated on by an arithmetic unit to calculate many time and phase conditions of the MSK digital data signal at one time and to produce third, fourth and fifth correlation signals as a function of assumed bit times. These third, fourth and fifth correlation signals are operated on by a ratio calculator to produce a ratio signal proportional to the ratio of a minimum magnitude squared to a maximum magnitude squared for all carrier phase angles for each of the assumed bit times. A synchronization detected signal is produced when the value of the ratio signal is less than a given amplitude threshold.

Frequency Hopping Synchronization And Tracking In A Digital Communication System

View page
US Patent:
60524065, Apr 18, 2000
Filed:
May 2, 1997
Appl. No.:
8/850231
Inventors:
Marvin A. Epstein - Monsey NY
Gary V. Blois - Towaco NJ
Joseph M. Fine - West Caldwell NJ
Assignee:
ITT Manufacturing Enterprises, Inc. - Wilmington DE
International Classification:
H04K 100
H04K 104
H04L 2730
H04L 700
US Classification:
375202
Abstract:
There is disclosed an improved frequency hopping synchronization and tracking system for bit syncing and frame syncing a digital data signal as transmitted by a radio transmitter. A detection means responsive to incoming data samples representative of the phasing signal portion of the digital data signal partitions the data samples into alternating first and second sample sequences and correlates the samples against a frequency hop modulation code reference sequence to provide an initial data signal detection. A post-detection means responsive to the initial detection and to the frequency hop modulation code reference sequence correlates the incoming data samples and compares the spectral power of the correlated data samples to a threshold value to provide bit sync of the detected data signal. Tracking means responsive to the bit sync and to the input samples captures a frame signal and generates histograms of data bit transitions for producing an error signal indicative of the difference of the transmitted clock rate and the sampling position of the received bit. A clock means responsive to the error signal produced by the histogram process can be adjusted according to the error signal to enable sampling of each received data bit to occur relatively at the center of each bit to ensure reliable decoding or detection of a digital data signal in a noisy channel at the receiver.

Chopping Correlator For A Msk Data Signal

View page
US Patent:
39926176, Nov 16, 1976
Filed:
Oct 1, 1975
Appl. No.:
5/618537
Inventors:
Marvin Aaron Epstein - Monsey NY
Assignee:
International Telephone and Telegraph Corporation - Nutley NJ
International Classification:
G06G 719
H04L 2714
US Classification:
235181
Abstract:
The MSK signal is distributed to eight choppers, each of which also has coupled thereto a different sum or difference cosine or sum or difference sine chopping signal. The output signals from the choppers are summed in selected pairs in summers whose output signals are integrated over a predetermined number of unit time intervals. Coupled between four of the summers and four of the associated integrators there is an integrated time selector which enables adjusting the integrator output for different baud rates of the MSK signal input. The output signals of the integrators are coupled in pairs of multiplexers whose output signals in turn are coupled to sample and hold circuits. The output signals of the sample and hold circuits are coupled to another multiplexer whose output signal is coupled to an analog-to-digital converter to provide the data carried by the MSK signal in digital form. The correlator will provide an output from the analog-to-digital converter at a steady rate of two correlation coefficient values per unit interval for a given baud rate.
