In this paper, we propose a channel estimation approach based on Bayesian compressive sensing that has the advantage of computation simplicity, noise robust to some extent and the sparse result. UWB channel estimation is absolutely vital to the design of the receiver and is predicament of the UWB system implement. We show that our proposed method relies on the time domain sparse of the impulse response...
To distinguish the polypus patients, the spectrum map of the speech samples is used to analyze. Compared the spectrum map with impulse response in wireless communication channel, statistical characteristic root-mean square-delay spread (RMSD) and standard deviation (SD) are employed to describe the speech frequency domain characteristic. Fuzzy logic system (FLS) is used to make polypus patients diagnosis...
