Abstract :
In this paper, a new trend of Space Time Block Code-Orthogonal Frequency Division Multiplexing (STBC-OFDM) was proposed. First, introduce brief description of the conventional (STBC-OFDM) scheme. Second, introduce the efficient and low complexity scheme of a STBC-OFDM, where both encoder and decoder lay in the time domain. This scheme does not require channel knowledge either at the transmitter or receiver. The decoding algorithm is based on generalized maximum-likelihood sequence estimation. The performance of the proposed scheme was investigated over two-tap Rayleigh fading channels. The simulation results show the performance of proposed STBC-OFDM scheme definitely outperforms conventional STBC-OFDM scheme on fading channel for different Doppler frequency (fD).
