To realize this objective, Mel-LP based speech analysis has been used in speech coding on the linear frequency scale by applying a first-order all-pass filter instead of a unit delay. To minimize the mismatch between training and test phases, Cepstral Mean Normalization (CMN) and Blind Equalization (BEQ) have been applied to enhance Mel-LP cepstral coefficient as an ...

The aim of this paper is the performance evaluation of Cyclic Redundancy Check (CRC) encoded fixed WiMAX system under different combinations of M-ary quadrature amplitude modulation techniques (QAM, 16-QAM and 64-QAM) and different communication channels AWGN and fading channels (Rayleigh and Rician). It offers both line of sight and non-line of sight ...

The 4-by-1 spatially multiplexed Turbo encoded system under investigation incorporates Quasi-orthogonal space-time block coding (Q-STBC) and ML signal detection schemes under QPSK, QAM, 16PSK and 16QAM digital modulations. The simulation results elucidate that a significant improvement of system performance is achieved in QAM modulation. The results are also indicative of noticeable system performance enhancement with increasing number of iterations in Turbo encoding/decoding scheme.
