Abstract

High speed data communications are in fact succeeded by MIMO based Alamouti technique. In order to meet the rapid developments in digital devices the mentioned technique could not meet the requirements, so there is a need to develop a new technique Conjugate Symmetric – Sequency ordered Complex Hadamard Transform (CS – SCHT) to meet the enhanced speeds of the digital devices is presented in this paper. This fast and efficient algorithm to compute the CS-SCHT is developed using sparse matrix factorization method, its computational load is examined and compared to that of Hadamard Transform (HT) and Sequency – ordered Complex Hadamard Transform (SCHT). The outcomes attained are compared with HT and SCHT based Alamouti OSTBC. A substantial enhancement of bit error rate (BER) is perceived from simulation results.
