Abstract	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. The results show that compared to the SRE technology, the PISL technology enables a fixed summation time for all multipath channels, and significantly enhances the performance of the monobit ADC WTR receiver. Therefore, PISL technology is a promising technology to compensate the information loss caused by monobit quantization insuring high-performance, power efficient, and low complexity implementation for TR-based UWB receivers.
