The system performance in terms of the sum ergodic rate is discussed. The sum ergodic data rate is the average sum of the achievable data rate of symbols symbol 1 and symbol 2. Closed-form and asymptotic expressions for the ergodic capacities of both symbols s1 and s2 are derived. Monte Carlo simulations are used to verify the obtained analytical expressions of the ergodic capacity. As can be seen, analytical results are in agreement with the Monte Carlo simulation results at high SNR values. The slight difference between the analytical results and the simulation results at low SNR values is a consequence of using the asymptotic expression.
