Claim of US Patent No. 10,368,327

1. A signal acquisition system comprising:an input adapted to obtain a received signal which 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;
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 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 signal time frame processor comprises:
a. a carrier frequency analyzer module 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 piece being indicative of data encoded in said time frame portion over a carrier frequency associated with said carrier-data piece; and
b. a convolution module 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; and
an output module configured and operable for outputting identification data indicative of identification of said code word in said signal;
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 output module is further adapted to output said time index.
