Coexisting Passive RIS and Active Relay Assisted NOMA Systems
Ao Huang, Li Guo, Xidong Mu +2
A novel coexisting passive reconfigurable intelligent surface (RIS) and active decode-and-forward (DF) relay assisted non-orthogonal multiple access (NOMA) transmission framework i…
Symbol Detection for Coarsely Quantized OTFS
Junwei He, Haochuan Zhang, Chao Dong +1
This paper explicitly models a coarse and noisy quantization in a communication system empowered by orthogonal time frequency space (OTFS) for cost and power efficiency. We first p…
A Golden Decade of Polar Codes: From Basic Principle to 5G Applications
Kai Niu, Ping Zhang, Jincheng Dai +2
After the pursuit of seventy years, the invention of polar codes indicates that we have found the first capacity-achieving coding with low complexity construction and decoding, whi…
Sphere Constraint based Enumeration Methods to Analyze the Minimum Weight Distribution of Polar Codes
Jinnan Piao, Kai Niu, Jincheng Dai +1
In this paper, the minimum weight distributions (MWDs) of polar codes and concatenated polar codes are exactly enumerated according to the distance property of codewords. We first…
Polar-Slotted ALOHA over Slot Erasure Channels
Zhijun Zhang, Kai Niu, Jincheng Dai +1
In this paper, we design a new polar slotted ALOHA (PSA) protocol over the slot erasure channels, which uses polar coding to construct the identical slot pattern (SP) assembles wit…
Approaching the Finite Blocklength Capacity within 0.025dB by Short Polar Codes and CRC-Aided Hybrid Decoding
Jinnan Piao, Kai Niu, Jincheng Dai +1
In this letter, we explore the performance limits of short polar codes and find that the maximum likelihood (ML) performance of a simple CRC-polar concatenated scheme can approach…
