Asymptotic Error Rate Analysis of EGC over Generalized Correlated Nakagami-m Channels

Abstract

Asymptotic symbol error rate is derived for multi- branch predetection equal gain combining over generalized correlated Nakagami-m fading channels. It is shown that asymptotic error rates over correlated branches can be obtained by scaling the asymptotic error rates over independent branches with a factor, det <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> (√R), where det(√R) is the determinant of matrix √R whose elements are the square root of the corresponding elements in the branch power covariance correlation matrix R.
