Digital Communications in Spatially Distributed Interference Channels.
Abstract
This report is concerned with the characterization of the structure and performance of digital communication systems operating in spatially distributed interference channels when a multi-element array processing capability is available. It represents one phase of a continuing investigation and covers the period 1 July, 1980 through 31 March, 1981. This report is organized into five parts. Part I describes an optimum receiver when a multi-element array capability is available and under specific and somewhat simplified modeling assumptions. The results are useful in demonstrating the subtle interactions between spatial and temporal processing characteristics of an optimum receiver, particularly the modulation/coding tradeoffs. Part II discusses some new reduced compexity soft-decision decoding algorithms for linear block codes while Part III describes some new rational-rate convolutional code constructions. Both of these should be useful in impulsive or burst interference environments. In Part IV we describe some results on the modeling and analysis of selected linear and nonlinear receiver structures in impulsive or burst noise channels. Finally, an outline of how multi-element adaptive array processing structures are to be incorporated into the RPI developed Interactive Communications Simulator (ICS) is provided in Part V.
