MATLAB Simulation of 2-Transmit 1-Receive Alamouti Code

This project implements a MATLAB simulation of the Alamouti code, a space-time coding technique used to enhance transmission efficiency and reliability in wireless communication systems. The Alamouti code operates on fundamental encoding principles by utilizing multiple antennas and time slots to achieve parallel data transmission and reception. Through this coding scheme, we can effectively reduce bit error rates and improve signal quality, thereby enhancing overall communication system performance. The MATLAB implementation will include: - Alamouti encoding algorithm that processes two consecutive symbols for transmission from two antennas - Channel modeling with Rayleigh fading to simulate wireless propagation effects - Maximum likelihood decoding implementation at the receiver side - Performance evaluation through BER (Bit Error Rate) versus SNR (Signal-to-Noise Ratio) analysis Key functions in the simulation will demonstrate: 1. Symbol pairing and orthogonal code matrix generation 2. Transmit diversity implementation using two transmit antennas 3. Received signal combining and detection algorithms 4. Comparative analysis between Alamouti-coded and uncoded systems This simulation serves to validate Alamouti code performance characteristics and provides a platform for further research into space-time coding techniques, including potential extensions to MIMO systems with additional antennas.
