摘要：

In order to solve the problem of high-speed sampling in OFDM based ultra wide band (UWB) systems, this paper provides an analysis of the applicability of two existing compressed sampling methods, namely random modulation (RD) and parallel segmented compressed sensing (PSCS), for analog signals. The optimized orthogonal matching pursuit algorithm is used for the known sparsity avoiding iterative operation. Simulations show that the PSCS scheme can reduce the sampling rate in OFDM-UWB systems effectively as compared to RD. The system based on PSCS achieves a performance significantly better than that of RD.
