Abstract:
1. A method of processing an input signal having encoded therein a plurality of symbols in the form of a packet using frequency modulation, wherein said plurality of symbols containing a repetitive sequence comprised in said plurality of symbols, said method comprising: receiving said packet containing said plurality of symbols; correcting a first symbol by a first frequency offset and a second symbol by a second frequency offset, wherein said first symbol and said second symbol are contained in said plurality of symbols and wherein said first frequency offset is not equal to said second frequency offset; estimating said first frequency offset and said second frequency offset, via a hardware estimator, by examining said repetitive sequence, wherein said repetitive sequence includes a first set of symbols and a second set of symbols which are respectively received in a first duration and a second duration, wherein each of said first duration and said second duration having a respective plurality of sub-durations, wherein said estimating comprises: decoding said first symbol and said second symbol after said correcting to generate a first decoded value and a second decoded value.
