Özet
In recent years, there has been growing interest in the study of Trellis Coded Modulation (TCM) for wireless communication systems. TCM is a powerful error-correction technique that can improve a communication system's Bit Error Rate (BER) performance. In particular, combining TCM with Multiple Input Multiple Output (MIMO) systems has shown great promise in improving BER performance in wireless communications. This paper presents a comparison study on the Bit Error Rate (BER) performance of 8-Phase Shift Keying (8-PSK) and 8-Quadrature Amplitude Modulation (8-QAM) TCM coded in a$2\mathrm{x}2$Orthogonal Space-Time Block Code (OSTBC)-Multiple Input Multiple Output (MIMO) system over Additive White Gaussian Noise (AWGN) and fading channels. The study uses extensive simulations to compare the BER performance of the two modulation schemes under different channel conditions. The results of the study show that TCM improves the overall system performance regardless of the channel type. Additionally, 8-PSK TCM performed slightly better in AWGN channels, while 8-QAM TCM performed better in fading channels. The study also finds that the$2\mathrm{x}2$OSTBC-MIMO system is viable for improving BER performance in wireless communications.
