Space Time Block Coding for High Data Rate Wireless Communication
M. Beema Mehraj · 2014
Wireless communication using multiple-input multiple-output (MIMO)systems enables increased spectral efficiency for a given total transmit power. MIMO stand for multiple inputs and multiple outputs. It is a system that uses several antennas at the transmitter and receiver links.multiple-input-multiple- output(MIMO)systemswith reduced complexity is considered. The transmit diversity scheme become more popular to solve multi-path fading problem which use multiple antenna at transmitter to improve reliable data transmission.This scheme called combination of spatial (antenna) and temporal processing known as space time block coding (STBC). Alamouti's STBC scheme is the most famous and popular one since the only STBC which can achieve both full diversity and full code rate. In current research, high data rate wireless communications, transmission rate is of major interest. The idea behind MIMOis that the signals on the transmit (Tx) antennas at one end and the receive (Rx) antennas at the other endare combined in such a way that the quality (bit-error rate or BER) or the data rate (bits/sec) of the communication for each MIMO user will be improved.
