Volume 7 No.1 January-June 2018 pp 37-42
In this paper we propose a systematic method for designing a space – time orthogonal MIMO scheme that employs an arbitrary number of transmitting and receiving antennas. Such systems is utilized to improve the bit error rate (BER) performance of wireless communication systems and counter the destructive effects of channel attenuation and alternative distortion phenomena and also propose a matrix method advance is proposed to maintain the orthogonal property, which is most essential, so that the channels may remain un correlated, due to this condition, interference do not occurs between the data transmitted through the channels and thus performance improvement is achieved, which is evaluated through simulation.
