摘要：

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