Claim:
1. A method for wireless communication, comprising: receiving complementary sequences; estimating a channel estimation of a channel based on the received complementary sequences; estimating a signal-to-noise ratio (SNR) estimation of the channel; detecting a maximum channel response of the channel estimation; computing a de-noised threshold based on the maximum channel response and the SNR estimation of the channel, wherein the de-noised threshold is computed by dividing the maximum channel response by the SNR estimation of the channel, and multiplying a resulting quotient by a threshold noise, wherein the threshold noise is representative of a known additive noise; comparing the de-noised threshold to the channel estimation to detect a last valid tap of a channel impulse response; and zeroing out one or more taps of the channel impulse response if the one or more taps are after the detected last valid tap of the channel impulse response.
