Performance of polar codes with the construction using density evolution
Ryuhei Mori,Toshiyuki Tanaka +1 more
TL;DR: This letter evaluates performance of polar codes designed with the new construction method, and compares it with that of the codes constructed with another heuristic method with linear complexity proposed by Arikan.

Performance and Construction of Polar Codes on Symmetric Binary-Input Memoryless Channels
Ryuhei Mori,Toshiyuki Tanaka +1 more
TL;DR: In this paper, a new construction method for arbitrary symmetric binary memoryless channel (B-MC) with linear complexity in the blocklength is proposed, and new upper and lower bounds of the block error probability of polar codes are derived for the BEC and the symmetric B-MC, respectively.

Performance and construction of polar codes on symmetric binary-input memoryless channels
Ryuhei Mori,Toshiyuki Tanaka +1 more
TL;DR: A new construction method for arbitrary symmetric binary memoryless channel (B-MC) with linear complexity in the blocklength is proposed and new upper bound and lower bound of the block error probability of polar codes are derived for the BEC and arbitrary asymmetric B-MC.
Proceedings ArticleDOI
Channel polarization on q-ary discrete memoryless channels by arbitrary kernels
Ryuhei Mori,Toshiyuki Tanaka +1 more
TL;DR: This paper considers more general channel polarization on q-ary channels, and shows explicit constructions using Reed-Solomon codes, on which asymptotically fast channel polarization is induced.
Proceedings ArticleDOI
Non-binary polar codes using Reed-Solomon codes and algebraic geometry codes
Ryuhei Mori,Toshiyuki Tanaka +1 more
TL;DR: In this paper, the error probability of non-binary polar codes constructed on the basis of Reed-Solomon matrices by numerical simulations was calculated and it was confirmed that 4-ary polar codes have significantly better performance than binary polar codes on binary-input AWGN channel.
