Abstract :
Using the results in the article by Win et al. (see ibid., vol.4, no.10, p.301-3, Oct. 2000) regarding the maximal ratio combiner for correlated Nakagami-m fading channels, we provide a simple analytic proof, applicable to a general class of modulation schemes, that uncorrelated branches result in a lower symbol error probability than do correlated branches.
