Performance of Rake Receiver Assisted Adaptive-Modulation Based CDMA over Frequency Selective Slow Rayleigh Fading Channels
A closed form expression of the average bit error rate (BER) is derived for a Rake receiver adaptive-modulation scheme over frequency selective slow Rayleigh fading channels. Multidimensional minimisation of a cost function based on the derived closed form BER expression is performed to optimise the switching levels for a constant BER adaptive modulation system.

Abstract

A closed form expression of the average bit error rate (BER) is derived for a Rake receiver adaptive-modulation scheme over frequency selective slow Rayleigh fading channels. Multidimensional minimisation of a cost function based on the derived closed form BER expression is performed to optimise the switching levels for a constant BER adaptive modulation system.
