Abstract
Diversity techniques have been used over the years to improve
the wireless communication links, mitigate fading, achieve
higher data rates, and improve channel capacity gains. This
paper presents the comparative analysis of transmitting and
receive diversity techniques with our proposed extended
Alamouti’s scheme using orthogonal space-time block codes
(OSTBC) under the Rayleigh faded channel. In this paper, three
possible diversity configurations have been considered:
multiple-input multiple-output (MIMO), single-input multiple
outputs (SIMO), and multiple-input single-output (MISO). The
model was developed in a Matlab environment and
performance comparison was carried out using BER vs SNR.
Our proposed model proved that the MIMO system is highly
efficient in improving wireless communication links. Also, our
proposed transmit diversity scheme with a higher number of
antenna arrays achieves full diversity as in receive combining
schemes
