Abstract
This paper presents the performance evaluation of
Orthogonal Space Time Block Codes on Multiple Input
Multiple Output (OSTBC-MIMO) system using our proposed
extended Alamouti’s STBC scheme based on Orthogonal
design. The model was evaluated with different modulation
schemes such as BPSK, QPSK, 8-PSK, and 16-PSK for different
antenna configurations. From our results, BPSK outperforms
other modulations scheme. The system model was developed
in Matlab environment and Bit error rate against signal to
noise ratio was used to evaluate the performance under
Rayleigh faded channel. Our proposed scheme improves the
channel capacity gains, data throughput, and mitigate fading
and interference.
