Performance Analysis of Space-Time Trellis Code on Rayleigh, Rician and Nakagami Fading Channel
Abstract:
Space-time codes merge coding gain with diversity gain and maintain orthogonality between the antennas. Coding works as a promising technique in the reliable digital data communication. STTC provides coding gain as well as diversity gain which gives the additional SNR advantage due to coding gain. This thesis analyzes the STTC over Rayleigh, Rician and Nakagami fading channel along with its implementation. STTC has been used for encoding and vitebri decoder for decoding. The design of 2-PSK for the SISO and use of 2 transmit antennas at transmitting side and use of receive antenna at receiving side up to 4 has been presented for 4, 8, 16 and 32 state. The result shows a significant improvement in performance of STTC with increasing number of states, number of transmit and receive antennas. It makes the data reliable and secured, along with increased throughput between the transmitter and receiver. It has been concluded that STTC over MIMO channel has improved error performance in terms of SNR with Nakagami fading channel.
