The Objective of the thesis is to evaluate and optimize the performance of two-way amplify-and-forward relay in the cellular context. With this, we have analyzed several performance measures such as outage probability, bit error rate, and ergodic sum-rate for various realistic scenarios over generalized fading channels. In addition, we have optimized the crucial design parameters such as, relay location and power allocation, for improving the overall performance of cellular multiuser ANC-based TWR systems. Further, we have evaluated secrecy outage performance of the considered system.
Objective of the thesis is to develop a scheme to authenticate the legitimate user in mobile environment. For this, GLRT hypothesis testing is used. The performance of the proposed methods is evaluated in a MIMO/OFDM scenario. MATLAB tool is used to develop this scheme.
