OPTIMAL RAKE RECEIVER MODEL UTILIZING TIME HOPPING IMPULSE RESPONSE ON UWB SYSTEM (WPAN)

Abstract

Impulse Radio-Time Hopping-Ultra Wideband (IR-TH-UWB) is a relatively new technology that might have a big effect on improving wireless communication. This technology uses short pulses in order to transmit large amounts of digital data over a wide spectrum of frequency bands with a very low power. This paper we derive the performance for UWB communication systems using different optimal models techniques in a RAKE Receiver. Comparisons have also been made between the techniques and conclusions have been drawn based on the requirements. We present simulation results using IEEE 802.15.3a UWB channel models. We evaluate the performances of Rake Receivers with different pulse-widths and also the effect of inter-frame interference in Ultra wideband Multipath Channels.
