Apparatus And Method For Digital Data Transmission Using Orthogonal Codes

View page
US Patent:
6356555, Mar 12, 2002
Filed:
Jul 19, 1996
Appl. No.:
08/684243
Inventors:
Selim Shlomo Rakib - Cupertino CA
Yehuda Azenkot - Cupertino CA
Assignee:
Terayon Communications Systems, Inc. - Santa Clara CA
International Classification:
H04B 169
US Classification:
370441, 370442, 370478, 370479, 370480, 370503
Abstract:
A method and apparatus for carrying out synchronous co-division multiple access (SCDMA) communication of multiple channels of digital data over a shared transmission media such as a cable television system coaxial cable, a fiber optic or copper conductor telephone link, terrestial microwave, satellite link, local or wide area network, wireless including cellur network or some combination of these media using suitable interface circuitry. The system includes modems at remote units and a central unit to receive time division multiplexed digital data arranged into timeslots or channels and uses orthogonal codes to encode each channel of multiple data and spread the energy of each channel data over a frame of data transmitted in the code domain. Spreading the data this way makes the system less susceptible to impulse noise. Frames are synchronized as between remote and central units using a ranging scheme which is also useful in any other system transmitting data by frames in a distributed system where synchronizing the frames as between all units regardless of differences in propagation delays is necessary.

Apparatus And Method For Equalization In Distributed Digital Data Transmission Systems

US Patent:
6665308, Dec 16, 2003
Filed:
Sep 17, 1998
Appl. No.:
09/156560
Inventors:
Selim Shlomo Rakib - Cupertino CA
Yehuda Azenkot - Cupertino CA
Assignee:
Terayon Communication Systems, Inc. - Santa Clara CA
International Classification:
H04B 138
US Classification:
370441, 370442, 370479, 370503, 375222, 375233
Abstract:
A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.

Multichannel, Multimode Docsis Headend Receiver

US Patent:
6791995, Sep 14, 2004
Filed:
Jun 13, 2002
Appl. No.:
10/172035
Inventors:
Yehuda Azenkot - San Jose CA
Selim Shlomo Rakib - Cupertino CA
Assignee:
Terayon Communications Systems, Inc. - Santa Clara CA
International Classification:
H04J 400
US Classification:
370436, 370447, 370462, 370538, 725117, 725144
Abstract:
A multichannel, mixed mode cable modem termination system receiver capable of receiving multiple channels of digital data transmitted on one or more hybrid fiber coaxial cable systems, each the channels being either single mode or mixed-mode. Mixed mode channels are time division multiplexed and have overlapping bandwidth and each sub-channel of a mixed mode channel can have a different center frequency, symbol rate and/or multiplexing type. The receiver is comprised of a plurality of analog front end circuits coupled to the various HFC systems, each selective coupled to any one of a plurality of digital front end receivers. Control circuitry controls these circuits to receive multiple mixed-mode or single mode channels, simultaneously if necessary. An arbiter decides which bursts get processed first in a back end shared demodulator which recovers the data from each burst. The preferred shared demodulator includes an equalizer, predictor and rotational amplifier which processes both TDMA and SCDMA data bursts post despreader to reduce reception data errors.

Detection Of Impulse Noise Using Unused Codes In Cdma Systems

View page
US Patent:
6859488, Feb 22, 2005
Filed:
Sep 25, 2002
Appl. No.:
10/255286
Inventors:
Yehuda Azenkot - San Jose CA, US
Zhenzhong Gu - Sunnyvale CA, US
Selim Shlomo Rakib - Cupertino CA, US
International Classification:
H04B001/69
H04B001/10
G10L019/12
US Classification:
375147, 375254, 704222
Abstract:
An impulse detector which can detect both low and high levels of impulse noise in a CDMA system is comprised of circuitry to calculate the background noise level in unused codes. Another circuit calculates the average noise power in the unused codes of each spreading interval to output the noise power per spreading interval. This average is continuously averaged over spreading intervals by another circuit which outputs the average background noise power. A comparator compares the noise power in the current spreading interval with the background noise power plus a programmable threshold and generates an erasure indication if the background noise power plus a discrimination threshold is exceeded.

Method And Apparatus To Improve Scdma Headroom

US Patent:
7002899, Feb 21, 2006
Filed:
Oct 9, 2001
Appl. No.:
09/974202
Inventors:
Yehuda Azenkot - San Jose CA, US
Selim Shlomo Rakib - Cupertino CA, US
Assignee:
ATI Technologies Inc. - Markham
ATI International S.R.L. - St. Michael
International Classification:
H04J 11/00
US Classification:
370208, 370252, 725107, 725129
Abstract:
A method of determining when cable modems in a distributed digital data delivery service over cable TV hybrid fiber coaxial cable network have a headroom problem and resolving said problem. The method involves measuring the burst power from each cable modem, and if the burst power is too low, requesting the cable modem whose burst power is too low to increase its transmit power, and keeping track of which modems have been requested to increase their power. If a predetermined number of requests to increase power have not resulted in the cable modem transmitting with sufficient power for reliable reception, the cable modem is listed as having a headroom problem. Subsequent requests for upstream bandwidth from all modems with headroom problems are analyzed to determine if the requested burst size is too large and will result in a headroom problem. If so, a calculation as to the maximum number of spreading codes that each modem with a headroom problem can simultaneously transmit on without a headroom problem. The requested burst is then broken down into smaller burst fragments, and appropriate upstream minislot assignments adequate to transmit the burst fragments are made and sent to the cable modem.
