ESTIMATING PAPER IN VARIABLE GAIN RELAYING ON IMPERFECT CSI

Amplify and Forward (AF) relaying, which refers to simple amplification and forwarding of the information sent from a source to destination terminal. For the conventional three node Amplify and Forward (AF) relaying setup, investigate the effect of imperfect channel state information (CSI) at the relaying on the overall performance. In particular, consider variable gain AF relaying and derive expression for the outage and the error probability and expression for the complimentary cumulative distribution function (CCDF) of the peak-to-average power ratio (PAPR) at the relay is calculated. The proposed method was drawn from a performance analysis for outage CSI at the relay. Finally the project work was simulated using the MATLAB software.
