Performance of combining techniques using rotated PSK over Nakagami-m fading channels

In this paper, improvements in symbol error probability (SEP)/bit error probability (BEP) performance of rotated phase shift keying (PSK) modulation using receive antenna diversity (combining) techniques are studied over frequency nonselective Nakagami-m slowly fading channels. Optimum rotation angles are obtained by the simulations. Effects of the rotation of signal consellations on the combining techniques (CT) are studied.
