In this paper, two novel digital signal processing technologies, denoted as Polarity-Invariant Square Law (PISL) technology and forgetting factor based Successive Reference Enhancement (SRE) technology, are proposed for Transmitted Reference (TR) based monobit receivers to compensate the quantization noise and enhance the quality of reference pulses. Since Weighted TR (WTR) system can achieve a superior performance as well as a high data-rate under severe multipath environments, the PISL and SRE technologies are applied to the WTR receiver over intra-vehicle channels.
