Abstract :

The Multiple Input Multiple Output (MIMO) system offers high transmission rate without the use of extra bandwidth and power. The principal goal of MIMO technology is to improve the quality, i.e. bit error rate (BER) by means of adequate signal processing techniques. This paper gives an overview of MIMO systems. Multiple antennas have been used to increase diversity to combat channel fading. Receive diversity techniques and transmit diversity techniques are studied and analysed. Inter Symbol interference (lSI) is a major problem even in MIMO systems. To mitigate lSI, equalization techniques are employed on the receiver side. Wireless relaying networks had recently been given considerable benefits over traditional communication system. The relaying terminals forward the information from the source to the destination mainly using the Amplify-Forward method. In this project achievable sum rate of multi way relaying with non re-generative relay (Amplify and forward) method is analyzed.
