Abstract

This paper presents a comparative analysis of dualbranch maximalratio combining MRC and equalgain combining EGC receivers with coherent modulations over correlated Weibull fading channels The numerical and simulations results show the influence of imperfect cophasing branch unbalancing and correlation on the error performance It is interestingly shown that EGC has lower irreducible error floor than MRC in the presence of incoherent combining while the higher value of the correlation coefficient results to lower irreducible error floor Furthermore the unbalance parameter has practically no influence on the irreducible error floor
