Femtocells are assuming an increasing important role to extend the cellular network coverage and provide high speed data service for indoor environments. To cope with the extreme interfering cases in the WCDMA uplink scenario, Home NodeB (HNB) receivers need to employ uplink attenuation at the RF frontend to suppress the interfering signals introduced by unattached co-channel users, e.g., a penetrating signal from macro-connected users in the proximity. The optimal level of uplink attenuation...[Show more]
