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.　©　2012　IEEE.
