Abstract :
This paper investigates the estimation of time varying channels for ultra-wideband (UWB) impulse radio communication. The channel parameters considered are the attenuations and delays incurred by the signal echoes along the different propagation paths. Time hopping using pulse position modulation (PPM) with binary symbols is assumed. The estimation method is based on Kalman estimation using pilot pulses. Simulation results for bit error rate (BER) performance of both multi-bit rake (MBR) and single-bit Rake (SBR) receivers, using Kalman based channel estimation, are presented
