Abstract :
Expressions of spectral efficiency have been obtained for optimal and suboptimal adaptive transmission techniques with uncoded MQAM (multilevel quadrature amplitude modulation) over Two Wave Diffuse Power (TWDP) fading channels. Probability density function of signal-to-noise ratio is used to obtain the expressions. A study of the effect of fading parameters on the spectral efficiency of different techniques has been presented.
