The estimation of receiving impulse template can be simplified by the transmitted reference (TR) signaling scheme in ultra-wideband communication. However, in multiuser environment, the TR scheme would be severely interfered for its non-coherence. By modulating the transmitted-reference with a pseudo-random code, we propose an analog LMS detection based on minimum mean-square error criterion to suppress the interferences. The method uses not only the waveform of the TR signal, but also its symbol information. The performance is further derived and the width of integration window is discussed.
