Effects of Single-Cycle Structure on Iterative Decoding for Low-Density Parity-Check Codes
Ryuhei Mori, Toshiyuki Tanaka, Kenta Kasai +1
We consider communication over the binary erasure channel (BEC) using low-density parity-check (LDPC) codes and belief propagation (BP) decoding. For fixed numbers of BP iterations…
Non-Binary Polar Codes using Reed-Solomon Codes and Algebraic Geometry Codes
Ryuhei Mori, Toshiyuki Tanaka
Polar codes, introduced by Arikan, achieve symmetric capacity of any discrete memoryless channels under low encoding and decoding complexity. Recently, non-binary polar codes have…
Properties and Construction of Polar Codes
Ryuhei Mori
Recently, Arıkan introduced the method of channel polarization on which one can construct efficient capacity-achieving codes, called polar codes, for any binary discrete memoryless…
Refined rate of channel polarization
Toshiyuki Tanaka, Ryuhei Mori
A rate-dependent upper bound of the best achievable block error probability of polar codes with successive-cancellation decoding is derived.
Channel Polarization on q-ary Discrete Memoryless Channels by Arbitrary Kernels
Ryuhei Mori, Toshiyuki Tanaka
A method of channel polarization, proposed by Arikan, allows us to construct efficient capacity-achieving channel codes. In the original work, binary input discrete memoryless chan…
