MATLAB Implementation of Space-Time Orthogonal Coding

The source program for space-time orthogonal coding is an encoding technique designed for wireless communication systems. The fundamental reference for this coding technique is the paper "Space-Time Block Codes from Orthogonal Designs" by V. Tarokh, H. Jafarkhani, and A. R. Calderbank, published in IEEE Transactions on Information Theory, Vol. 45, No. 5, July 1999. This paper provides detailed explanations of the principles and applications of space-time orthogonal coding algorithms. The MATLAB implementation involves constructing orthogonal design matrices that enable simultaneous transmission from multiple antennas. Key functions include: - Generation of complex orthogonal matrices satisfying the orthogonality condition for transmit diversity - Mapping of input symbols to spacetime codewords using algebraic formulations - Computation of coding gain through determinant criteria for optimal performance By employing space-time orthogonal coding, wireless communication systems can achieve enhanced transmission performance and improved interference resistance, resulting in more reliable data transmission through diversity techniques and maximum-likelihood decoding implementations.
