Signal space representation of indirect cochannel interference canceller

Abstract

The BER performance of a previously proposed indirect cochannel interference canceller (ICIC) in the AWGN channel, is explained by signal space representation. Except for a special case, a fully geometrical representation is not possible. Minimum signal envelope distance has been exploited to explain some of the ICIC receiver's performance. The effect of different parameters on the minimum envelope distance is investigated.
