  • A novel differential detection method, called Frequency Domain Spread Spectrum Chip-Level Differential Detection (FD-SS-CLDD) is proposed in frequency domain spread spectrum system. The Moment Generating Function (MGF) of decision variable and a saddle point approximation method are exploited to analyze the BER performance of FD-SS-CLDD, and the theoretical results are evaluated by simulation. If the coherent bandwidth of channel does not exceed the occupied bandwidth of two chips, with the increase of delay spread of the channel, FD-SS-CLDD exhibits a better performance to make the system resistant to frequency-selective fading.
