Performance analysis of Novel coding technique suitable for time varying Wireless Communication Systems using Multiple Input Multiple Output

Abstract

This paper presents highly robust coding technique suitable for multiple-input multipleoutput (MIMO) system. MIMO seems to be the only solution for today’s hostile wireless communication
system. It has been found that the use of multiple antennas at either transmitter or receiver greatly
improves the reception of Rayleigh faded signal. So time is to search for coding technique suitable for
MIMO environment. This work presents Space Frequency Block Coding (SFBC) technique that
improves the performance of multipath signals of wireless communication systems. it can be observed by
the analysis of space time block codes (STBC) and SFBC that SFBC is the close choice of MIMO as far
as frequency faded channel is concerned. This work discusses the combinations of multiple antennas at
either transmitter and or receiver and shows that increase in number of antennas gives rise to bit error
rate (BER) which is one of the important measure of link reliability.To show the conclusion, comparison
has been using SFBC coded three transmit and multiple receive antennassystems. It is found that SFBC
coding plays important role in increasing data rate and provide diversity gain and as the number of
antennas increases either in transmitter or in receiver side, it provides diversity gain. Thisgreatly
improves the performance of wireless communication channel in Rayleigh faded environment.
