A Low Complexity FFT-based Algorithm for Channel Estimation of Ultra-Wideband Communication Systems

This paper describes a general windowing method to improve the channel estimation of ultra-wideband communication systems, then proposes a new low-complexity channel estimation algorithm which can effectively resist the inter-symbol interference. The algorithm can resist the inter-symbol interference caused by the channel impulse response. The algorithm only requires a 32-point FFT module. It is verified that the algorithm can effectively reduce the interference caused by multi-path channel and noise.
