Experimental and theoretical bit error rate performance evaluations of blind and nonblind training techniques are obtained by using a single-carrier WiMAX (IEEE 802.16-2004) radio for high-order quadrature amplitude modulation channels. Instead of using a certain type of channel profile, this study concentrates on true frequency-selective Rayleigh fading channels and also evaluates the fast fading scenario of Rayleigh channels in a real-time WiMAX radio environment around 3.5 G Ph. The popular least mean squares (LMS) learning algorithm, and constant modulus learning algorithm (CMA) are used as benchmarks in an. investigation of nonblind and blind trainings, namely recursive least, Squares (RLS), modified-CMA, normalized-CMA, and fuzzy-CMA. The simulation results demonstrate that the theoretical and experimental studies are compatible with each other and extremely satisfying.
