Joint Constellation Rotation and Symbol-level Precoding Optimization in the Downlink of Multiuser MISO Channels
Maha Alodeh, Björn Ottersten
This paper tackles the problem of the simultaneous interference among the multiple users in the downlink of a wireless multiantenna system. In order to exploit the multiuser interf…
Symbol-level and Multicast Precoding for Multiuser Multiantenna Downlink: A Survey, Classification and Challenges
Maha Alodeh, Danilo Spano, Ashkan Kalantari +4
Precoding has been conventionally considered as an effective means of mitigating the interference and efficiently exploiting the available in the multiantenna downlink channel, whe…
Symbol-Level Multiuser MISO Precoding for Multi-level Adaptive Modulation
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
Symbol-level precoding is a new paradigm for multiuser downlink systems which aims at creating constructive interference among the transmitted data streams. This can be enabled by…
Joint Channel Estimation and Pilot Allocation in Underlay Cognitive MISO Networks
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
Cognitive radios have been proposed as agile technologies to boost the spectrum utilization. This paper tackles the problem of channel estimation and its impact on downlink transmi…
Symbol Based Precoding in The Downlink of Cognitive MISO Channels
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
This paper proposes symbol level precoding in the downlink of a MISO cognitive system. The new scheme tries to jointly utilize the data and channel information to design a precodin…
Energy Efficient Symbol-Level Precoding in Multiuser MISO Channels
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
This paper investigates the idea of exploiting interference among the simultaneous multiuser transmissions in the downlink of multiple antennas systems. Using symbol level precodin…
