In 3GPP GERAN, the performance specification of dual-antenna interference suppression techniques will be a subject of the downlink advanced receiver performance (DARP) phase II work item. In this study, we apply a filter-based single antenna interference suppression technique for downlink GSM 8PSK modulation assuming the terminal is equipped with two antennas. We evaluate the performance using a correlation-based spatial channel model and show the potential of suppressing the co-channel interference even for high correlation factors. Besides, a performance improvement can be observed if the phase angles of the correlation factors for the desired user and interferer are different in highly spatially correlated channels
