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…
Progressive Rate-Filling: A Framework for Agile Construction of Multilevel Polar-Coded Modulation
Jincheng Dai, Jinnan Piao, Kai Niu
In this letter, we propose a progressive rate-filling method as a framework to study agile construction of multilevel polar-coded modulation. We show that the bit indices within ea…
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…
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…
