Diversity Analysis for Frequency-Selective MIMO-OFDM Systems With General Spatial and Temporal Correlation Model
Overview In this paper, the effect of a general spatial and temporal fading correlation structure on the performance of coded MIMO-OFDM systems is studied. The analysis handles an arbitrary joint transmit-receive spatial correlation model including the non-Kronecker model. An upper bound on the maximum achievable diversity order for frequency-selective MIMO-OFDM systems with general temporal and spatial correlation is derived. Furthermore, a space-time-frequency code design that can achieve the upper bound for any arbitrarily correlated channel scenario is provided. The general framework of the analysis includes space-frequency coded systems as a special case. For the space-frequency coded MIMO-OFDM system, it is shown that any space-frequency code designed to achieve full diversity in the independent fading channel can achieve full diversity in an arbitrary spatially correlated channel.
