Implementation of Space-Time Block Coding (STBC) Using 2 Transmit and 2 Receive Antennas

MIMO wireless technology has grown in the last few years. MIMO technology was mainly used for the analysis of channel capacity and also lead to the research for MIMO channel model, Space-Time coding. A signaling technique called Space-Time coding uses the MIMO structure to improve the robustness of communication link. Space–time block codes are designed to achieve the maximum diversity order for a given number of transmit and receive antennas subject to the constraint of having a simple decoding algorithm. This paper presents the Simulation results of 2 Transmit and 2 Receive antennas of Alamouti Scheme. Keywords— Alamouti Scheme, Transmit Diversity, Multiple-Input Multiple-Output (MIMO), Multipath Fading, Space-Time Block codes.
