Abstract :Experimental and theoretical bit error rate performance evaluations of blind and nonblind training techniques are obtained by using a single-carrier WiMAX insert ignore into journalissuearticles values(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 GHz. The popular least mean squares insert ignore into journalissuearticles values(LMS); learning algorithm and constant modulus learning algorithm insert ignore into journalissuearticles values(CMA); are used as benchmarks in an investigation of nonblind and blind trainings, namely recursive least squares insert ignore into journalissuearticles values(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.
