For high data transmission over wireless fading! channels, STBC provide the maximal possible diversity advantage for multiple decoding algorithm. We present continuous phase modulation (CPM) for ST-TTC signal. mince CPM provided low-Spectral occupancy and is suitable for power and bandwidth-limited channels. In our model. to utilize STBC efficiently. we need to estimate the channel parameters. which influence the signals having continuity property. Therefore, we develop a blind maximum likelihood channel estimation algorithm for signal propagating through a Rician fading channel. Here. Baum-Welch (BW) algorithm based on hidden Markov model (HMM) is modified to provide computationally efficient channel parameter estimation. We also investigate the performance of ST-TTC/CPM in the case of no channel state information (CSI) for various Rician parameters K and Doppler frequency.
