摘要: Multiple access (MA) in UWB communication has recently been studied the context of multiple transmitted-reference short duration chirp pulses presence additive white Gaussian noise (AWGN). The (TR) receiver was extended previous studies using orthogonal pulses. Improved performance observed simulations by sampling autocorrelation function (ACF) at both zero- and non-zero lags. Sampling ACF lags is a novel approach. Method least squares filtering techniques for further tolerance against interference TR method proposed.
