This paper deals with the design of sub-optimal detectors in an interference channel with fading and with Additive White Gaussian Noise (AWGN). Parallel interference detector (PIC) is one of the Multiuser Detection (MUD) techniques, where it employs canceling or suppressing interfering users from the desired signals. The conventional detectors typically either ignore the interference or treat other user interference (Multiple Access Interference) as merely noise. But Multiple Access Interference (MAI) has a structure which can be exploited in the detection process. This paper quantifies the significant performance gain if the detector exploits the MAI structure through Multiuser detection technique, which not only improves the capacity of the channel but also reduce requirement for power control. The simulation result shows the better performance of PIC detector over conventional detector.
