Abstract
This paper investigates the performance of amplify-and-forward (AF) two-way relay system with antenna correlation. Overall outage probability (OOP), average symbol error rate (SER) and ergodic capacity are analyzed. By considering general correlation structure with arbitrary eigenvalue distribution, we derive a tight lower bound for OOP and use it to evaluate average SER and ergodic capacity. Moreover, the system is studied in high signal-to-noise ratio (SNR) to obtain the insightful behavior of the performance and diversity gain. Finally Monte Carlo simulations are conducted to verify the accuracy of the results.
