Co-Channel Interference Separation

Abstract

The objective of this effort was to investigate techniques to reduce the signal degradation due to co-channel and adjacent-channel voice-on-voice interference. Sorting and suppression techniques using linear prediction coefficients and an adaptive comb filter were investigated. Limited success was achieved. A procedure for estimating the frequency shift due to mistuning was developed.
