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…
Constructive Interference through Symbol Level Precoding for Multi-level Modulation
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
The constructive interference concept in the downlink of multiple-antenna systems is addressed in this paper. The concept of the joint exploitation of the channel state information…
Energy-Efficient Symbol-Level Precoding in Multiuser MISO Based on Relaxed Detection Region
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
This paper addresses the problem of exploiting interference among simultaneous multiuser transmissions in the downlink of multiple-antenna systems. Using symbol-level precoding, a…
