Performance Analysis and Approximate Message Passing Detection of Orthogonal Time Sequency Multiplexing Modulation
Zeping Sui, Shefeng Yan, Hongming Zhang +4
In orthogonal time sequency multiplexing (OTSM) modulation, the information symbols are conveyed in the delay-sequency domain upon exploiting the inverse Walsh Hadamard transform (…
Low Complexity Detection of Spatial Modulation Aided OTFS in Doubly-Selective Channels
Zeping Sui, Hongming Zhang, Yu Xin +3
A spatial modulation-aided orthogonal time frequency space (SM-OTFS) scheme is proposed for high-Doppler scenarios, which relies on a low-complexity distance-based detection algori…
Antenna Array Diagnosis for Millimeter-Wave MIMO Systems
Siqi Ma, Wenqian Shen, Jianping An +1
The densely packed antennas of millimeter-Wave (mmWave) MIMO systems are often blocked by the rain, snow, dust and even by fingers, which will change the channel's characteristics…
Polar-Precoding: A Unitary Finite-Feedback Transmit Precoder for Polar-Coded MIMO Systems
Jinnan Piao, Kai Niu, Jincheng Dai +1
We propose a unitary precoding scheme, namely polar-precoding, to improve the performance of polar-coded MIMO systems. In contrast to the traditional design of MIMO precoding crite…
Is NOMA Efficient in Multi-Antenna Networks? A Critical Look at Next Generation Multiple Access Techniques
Bruno Clerckx, Yijie Mao, Robert Schober +7
In this paper, we take a critical and fresh look at the downlink multi-antenna NOMA literature. Instead of contrasting NOMA with OMA, we contrast NOMA with two other baselines. The…
Dynamic Hybrid Precoding Relying on Twin-Resolution Phase Shifters in Millimeter-Wave Communication Systems
Chenghao Feng, Wenqian Shen, Xinyu Gao +2
Hybrid analog/digital precoding in millimeter-wave (mmWave) multi-input multi-ouput (MIMO) systems is capable of achieving the near-optimal full-digital performance at reduced hard…
