This paper presents the impact of frequency diversity on the optimum expected
end-to-end distortion (EED) in an outage-free wideband multiple-input
multiple-output (MIMO) system. We provide the closed-form expression of optimum
asymptotic expected EED comprised of the optimum distortion exponent and the
multiplicative optimum distortion factor for high signal-to-noise ratio (SNR).
It is shown that frequency diversity can improve EED though it has no effect on
ergodic capacity. The improvement becomes slight when the frequency diversity
order is greater than a certain number. The lower bounds related to infinite
frequency diversity are derived. The results for outage-free systems are the
bounds for outage-suffering systems and they are instructive for system design. |
