Design of UWB pulse radio transceiver using statistical correlation technique in frequency domain

[摘要] In this paper, we propose a new technique to extract low power UWB pulseradio signals, near to noise level, using statistical correlation techniquein frequency domain. The receiver consists of many narrow bandpass filterswhich extract energy either from transmitted UWB signal, interferingchannels or noise. Transmitted UWB data can be eliminated by statisticalcorrelation of multiple bandpass filter outputs. Super-regenerativeoscillators, tuned within UWB spectrum, are designed as bandpass filters.Summers and comparators perform statistical correlation.
