Abstract :
This paper presents an ergodic capacity analysis of an amplify-and-forward (AF) multiple-input, multiple-output (MIMO) two-hop, two relay system. We first derive an expression for the probability density function of an arbitrary eigenvalue of the system. Then, using this result, a closed form expression for the ergodic capacity of the system is derived. We present simulation results to validate our analysis. We also show that the results for a single relay system can be obtained as a special case.
