Abstract
An alternative method to channel estimation is presented as a means of supplying a RAKE receiver with the coefficients for Maximal Ratio Combining (MRC). The proposed RAKE receiver utilizes Time-Hopping Pulse Position Modulation (TH-PPM), and is specifically designed to be used in Ultra Wideband (UWB) communication systems in which channel estimation becomes problematic because of the high sampling rate required. The MRC coefficients are determined by a simple process of averaging the received energy for a given correlator finger over the course of a pilot sequence of P pulses. Performance of the proposed RAKE receiver is investigated through simulation using a discrete-time implementation of the multi-path channel model published by the IEEE 802.15.3 task group. The proposed RAKE receiver’s Bit-Error-Rate (BER) performance is compared against other RAKE receivers relying on channel estimation.
