We propose a novel approach to demodulate time-hopping pulse position modulated (PPM) impulse radio signals using a fully digital receiver. The pulses are viewed as non-uniform samples of an underlying continuous signal. They are then interpolated and consistently uniformly resampled using an appropriate kernel. A non-uniformly sampled signal is consistently resampled if the original samples can be...
The most computationally intensive part of the wideband receiver of a software defined radio (SDR) is the channelizer since it operates at the highest sampling rate. Higher order FIR channel filters are needed in the channelizer to meet the stringent adjacent channel attenuation specifications of wireless communications standards. In this paper, we present a coefficient-partitioning algorithm for...
