Sufficient Statistic and Reduced Dimensionality Equivalent Symbol Space Model for Frequency Flat MIMO Channel with Spatially Nonuniform Delay

Original language description

We first derive an equivalent symbol space discrete channel model for frequency flat block fading MIMO spatial diversity channel with spatially nonuniform path delays. A general nonlinear modulation scheme is assumed by allowing channel symbols to be multidimensional per one antenna. The sufficient symbol spaced statistic dimensionality is shown to be a product of transmit, receive and symbol dimensions unlike for a traditional frequency flat MIMO model where the dimension is a product of receive and symbol dimensions. The traditional model is valid only for spatially uniform delays. We show that the spatially nonuniform path delays cause spatial Inter-Branch Interference (IBI).We introduce a reduced dimensionality equivalent system. The spatial IBI can be reduced using Linear Minimum Mean Square Error (LMMSE) spatial-temporal preprocessing (equalizer).
