Abstract :
In this paper, we develop several increasingly tight and restrictive performance bounds for OFDM based MIMO wireless communication systems. Starting with channel capacity as the ultimate upper bound on the throughput, step by step we develop tighter bounds on the practically achievable throughput by incorporating typical design constraints. The presented bounds are applied to a Long Term Evolution system, allowing us to identify dominant sources of performance losses. The investigation reveals flaws of wireless communication systems thereby pointing at directions to efficiently improve performance in system design.
