Demodulating BOC signals using compressive signal processing

Abstract

In order to lower the sampling frequency of binary offset carrier(BOC) signal, a BOC signal demodulation scheme based on compressive signal processing is proposed. This method can reduce A/D sampling rate and system power consumption, and the hardware structure is simpler than in other systems.The numerical results show that compressed sensing can be successfully applied in BOC signal receiver. Affected by noise folding, BOC receiver of compressed signal processing has a slightly lower performance than traditional receiver, and its advantage is to reduce the complexity of implementation. Considering the quantization of the signal, noise folding has a much smaller effect on the performance of the receiver.
