CO-CHANNEL INTERFERENCE RECEIVER

摘要

A digital receiver (10) automatically detects and non-coherently demodulates a multiplicity of interfering digitally modulated signals transmitted simultaneously at approximately the same carrier frequency. The receiver (10) includes one or more antenna inputs (e.g., polarization and/or space diverse) (13), a parameter estimator module (20), and a multiuser detector (18) for estimating the data transmitted by each interfering signals and adapted to operate with at least one of a MUD algorithm with partially quantized prior information and a MUD algorithm based on prewhitened data.
