Optimal maximal ratio combining with correlated diversity branches
Xiaofei Dong, Norman C. Beaulieu · IEEE Communications Letters · 2002
It is proved that a maximal ratio combiner operating on correlated branches and weighting the branch signals as though they were independent is optimal. It is also proved that performance measures of maximal ratio combining operating with correlated Rayleigh or Ricean fading input branches are identical to performance measures of an equivalent diversity system operating with independent and, in general, unbalanced inputs.
