摘要：

This paper presents a comparative analysis of dual-branch maximal-ratio combining (MRC) and equal-gain 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.
