BER analysis of amplify and forward scheme with Best relay selection in Space Shift Keying System

Recently Space Shift Keying modulation(SSK) technique got attention in the world of wireless communications. To improve the performance of SSK systems few cooperative techniques are embedded in SSK systems. This paper presents Amplify and Forward scheme with Best relay selection in SSK systems. This proposed scheme,selects the Best relay based on available Signal to noise ratios at the destination. The performance of the proposed scheme is analyzed by finding the expression for Bit Error Rate(BER).Further more comparison on BER is taken by increasing the number of relays and placing at different positions like equal distance from source to destination, away from the source. Simulations have done to check the validity of analytical results.
