Abstract

In this paper, a new trend of Space Time Block codes-Orthogonal Frequency Division Multiplexing (STBC-OFDM) with Convolutional and Turbo codes. The applied method is based on Alamouti´s scheme. We examine the performance of two, three and four transmitters with one receiver over Nakagami-m fading channel using convolutional and turbo codes using different types of modulation such as BPSK and 64-QAM . Also we examine their performance using turbo code with different rates (1/2, 1/3) at BPSK. The performance of two transmitters with two receivers is also shown using convolutional and turbo codes over Nakagami-m fading channel at BPSK.
