Analysis of OSTBC for MIMO Rayleigh and Rician Channels

Abstract

Compared to a conventional single antenna , the channel capacity of a multiple antenna with NT transmitters and NR receiver antennas output is  amplified by a factor of min(NT, NR), without using supplementary transmission of power or spectral bandwidth. Due to the rising insist of more rapidly data transmission speeds in latest or future communication systems, multiple antenna  contain  actively investigated and successfully deployed in the up-and-coming broadband wireless access networks for example, Mobile Wireless Worldwide Interoperability for Microwave Access. MIMO technology is classified into two main categories: diversity and spatial multiplexing. The diversity techniques mean to receive the same information carriage signals in multiple antennas or to broadcast them from multiple antennas, thereby civilizing the efficiency of transmission uniformity. In the multiplexing techniques such as spatial, on the other hand, the several information streams are concurrently transmitted by the multiple antennas, thereby achieving a higher transmission speed.
