Impulse Radio Demodulation Scheme for Impulse Radio UWB Receiver

摘要

A new demodulation scheme for BPSK modulated first order derivative Gaussian pulses is proposed. The scheme first transfers the BPSK modulated data into the corresponding PWM modulated data, and filters out the narrower pulses to differentiate "0" and "1" state. The key idea of this method is based on detecting the modulated data pulse width. According to analysis of relevant paper, this method will fit the near field inductive coupling system for use like chip to chip wireless communication or centimeter range multimedia communications application. The simulation result shows that this demodulation method works well and supports hundreds of Megabits data rate (500 Mbps).
