The channel impulse response （CIR） is the core problem for the research of ultra wideband signal transmit characteristics. The time-domain deconvolution algorithm clean of the post data processing methods is improved which reducing the difficulty of the template signal acquiring procedure and simplifying the extraction process of channel impulse response. Then using this algorithm to apply to measurement date of indoor environment, the CIR is extract accurately, it can provide a reliable channel impulse response to the analysis of propagation characteristics of signal for following chapter.
