Abstract
One of the diversity configurations is transmit diversity. It is employed to mitigate multipath
fading channel in a time varying channels to improve wireless communication system and
make it more reliable. This paper presents a review of diversity techniques and
configurations with various signal processing techniques and space time coding system that
are mostly employed, diversity combining schemes and analysis of diversity schemes is also
exploited. We also proposed a robust space time coding scheme based on orthogonal design
by extending the Alamouti’s space time block coding to a higher order diversity and
evaluates its performance based on signal to noise ratio (SNR) and bit error rate (BER). The
advantage of this transmit diversity is to simplify the hardware requirement by providing a
cost effective solution in broadband wireless system with eliminating the need for adopting
many antennas at the receiver side
