摘要
分析了采用DS-BPSK调制方式的UWB通信系统非相干接收方案,并研究了一种以差分能量检测非相干接收方式为基础的非相干接收处理算法,在此基础上进行了非相干接收方式下DS-BPSK UWB系统的性能分析,并利用Matlab进行了仿真。仿真结果表明:本文所讨论的非相干接收算法对同步误差不敏感,可以很好地适用于不能精确同步的通信场合。
A non-coherent demodulation algorithm for DS-BPSK utral-wide-band（UWB） communication system is analyzed to deduct an academic formula for calculating the bit error probability of the DS-BPSK UWB scheme. The result simulation with Matlab approves the academic formula and shows that the algorithm is sensitive to timing offset. Thus it can be well applied to some nonsynchronous communication occasions.
