Downlink Asynchronous Non-Orthogonal Multiple Access with Quantizer Optimization
Xun Zou, Mehdi Ganji, Hamid Jafarkhani
In this letter, we study a two-user downlink asynchronous non-orthogonal multiple access (ANOMA) with limited feedback. We employ the max-min criterion for the power allocation and…
Trellis-Coded Non-Orthogonal Multiple Access
Xun Zou, Mehdi Ganji, Hamid Jafarkhani
In this letter, we propose a trellis-coded nonorthogonal multiple access (NOMA) scheme. The signals for different users are produced by trellis coded modulation (TCM) and then supe…
Cooperative Asynchronous Non-Orthogonal Multiple Access with Power Minimization Under QoS Constraints
Xun Zou, Mehdi Ganji, Hamid Jafarkhani
Recent studies have demonstrated the superiority of non-orthogonal multiple access (NOMA) over orthogonal multiple access (OMA) in cooperative communication networks. In this paper…
A New Codebook Design for Analog Beamforming in Millimeter-wave Communication
Mehdi Ganji, Hongbing Cheng, Qi Zhan +1
In this study, we analyze the codebook design used for analog beamforming. Analog beamforming and combining suffer from a subspace sampling limitation, that is, the receiver cannot…
Novel Time Asynchronous NOMA schemes for Downlink Transmissions
Mehdi Ganji, Hamid Jafarkhani
In this work, we investigate the effect of time asynchrony in non-orthogonal multiple access (NOMA) schemes for downlink transmissions. First, we analyze the benefit of adding inte…
On the Performance of MRC Receiver with Unknown Timing Mismatch-A Large Scale Analysis
Mehdi Ganji, Hamid Jafarkhani
There has been extensive research on large scale multi-user multiple-input multiple-output (MU-MIMO) systems recently. Researchers have shown that there are great opportunities in…
Interference Mitigation Using Asynchronous Transmission and Sampling Diversity
Mehdi Ganji, Hamid Jafarkhani
In this paper, we show that by investigating inherent time delays between different users in a multiuser scenario, we are able to cancel interference more efficiently. Time asynchr…
