Abstract

The present invention provides communication technology (transmitter and receiver systems) for communicating data from the transmitter to one or more terminals' receivers over one or more communication channels. The communication channel is transmitted in burst communication mode such that transmission signal includes transmission data time slots at which one or more of said communication frames are encoded in the signal and one or more recess time slots between them. The communication receiver is adapted for processing signals of the burst mode communication channel and is operable for processing at least a portion of a signal received in the communication channel after a recess time period during which communication frames were not transmitted to determine a carrier frequency of the communication channel, based on a single communication frame appearing in the communication channel after the recess time period.

Claims18

Dependent claims

A communication receiver adapted for processing signals of a burst mode communication channel from a remote communication system, wherein the communication receiver is configured and operable for processing at least a portion of a signal received in said communication channel after a recess time period during which communication frames were not transmitted in said communication channel to determine a carrier frequency of said communication channel, based on a single communication frame appearing in the communication channel after said recess time period;

wherein the communication receiver comprises an input adapted to receive said signal and a signal time frame processor connectable to the input and configured and operable for continuous processing of time frame portions of the received signal to identity at least one code word of a group of one or more predetermined code words, being encoded in a time frame portion of the received signal;
said signal time frame processor comprising:
a. a carrier frequency analyzer configured and operable for analyzing said a time frame portion of the received signal in conjunction with said plurality of possible carrier frequencies simultaneously, by transforming said time frame portion to generate carrier-data including a plurality of carrier-data-pieces associated with each possible carrier frequency of said plurality of possible carrier frequencies respectively, whereby each of said carrier-data pieces being indicative of data encoded in said time frame portion over a carrier frequency associated with said carrier-data piece;
and
b. a convolver configured and operable for processing the time frame portion of the signal to simultaneously identify whether said time frame portion encodes said at least one code word, over any one of said a plurality of possible carrier frequencies;
wherein said time frame processor is adapted to determine a time index of said code word in the received signal based on said time frame portion of the received signal at which said code word is identified;
and wherein said communication receiver further comprises an output adapted to output said time index.

4 more elements

A method of receiving signals comprising:

receiving signals transmitted in a burst mode communication channel from a remote communication system;
processing at least a portion of a signal received in said communication channel after a recess time period during which communication frames were not transmitted in said communication channel;
and
determining a carrier frequency of said communication channel, based on a single communication frame appearing in the communication channel after said recess time period;
wherein said signal being received encodes communicated data over a certain unknown carrier frequency, being any one of a plurality of possible carrier frequencies residing within a predetermined frequency band;
and
wherein the method comprises processing time frame portions of the received signal to identify at least one code word of a group of one or more predetermined code words, being encoded in a time frame portion of the received signal;
said processing of the time frame portions comprising:
a. analyzing a time frame portion of the received signal in conjunction with said plurality of possible carrier frequencies simultaneously;
and
b. convolving the time frame portion of the signal with at least one code word to simultaneously identify whether said time frame portion encodes said at least one code word, over any one of said plurality of possible carrier frequencies;
c. determining a time index of said code word in the received signal based on said time frame portion of the received signal at which said code word is identified.
