In this paper a new time domain approach which combines time reversal (TR) and downlink spatial beamforming (BF) is proposed that can result in WB/UWB Interference Mitigation (IM). In order to design the TR filter and the desired beams, the Channel State Information (CSI) between the UWB system and the other wideband (WB) victim users is required. This information is obtained using a hybrid Electromagnetic...
Receive beamfoming techniques play an important role in MIMO communications systems as means to mitigate interference and enhance the link quality. Multipoint receive beamforming methods are expected to provide additional gains in systems employing advanced coordinated multipoint processing. Due to its importance, receive beamforming has been studied extensively in the literature. The optimal detection...
This paper proposes a hybrid transmission technique based on adaptive code-to-user allocation and linear precoding for the downlink of phase shift keying (PSK) based multi-carrier code division multiple access (MC-CDMA) systems. The proposed scheme is based on the separation of the instantaneous multiple access interference (MAI) into constructive and destructive components taking into account the...
