基于PN编码器的压缩感知超宽带信道估计
UWB Channel Estimation Based on PN-encoder Filter Compressive Sensing
摘要
Abstract
A new method for ultra-wideband ( UWB) channel estimation based on compressive sensing (CS)is developed in this paper. PN encoder will be introduced to the CS framework. Quasi-Toeplitz matrix generated by the encoder is used to instead of fully random Gaussian matrix. Because encoder can store some information,measurement operators can be stored and applied efficiently in the encoder and the problem of large data compression also can be solved. In addition,the encoder is easily implementable in software or hardware. Follow the theory of time reversal .most energy consumption and computation of the processing at the receiver can be moved to the transmitter. Finally the receiver complexity is reduced and data processing is speeded up.关键词
