| Abstract: | Based on the difference detection principle,an algorithm is presented for achieving fast demodulation of FSK signals in software radio. Theoretical analysis and simulation results verify the efficiency of this algorithm. Comparing with digital quadrature demodulation algorithm, it has nice properties such as no need to resume local carrier recovery, easier to realise and less computation cost. Thus it can satisfy the requirements of demodulation algorithm in sofeware radio. |
