Partial Orders in Rate-Matched Polar Codes
Zhichao Liu, Liuquan Yao, Yuan Li +4
In this paper, we establish the partial order (POs) for both the binary erasure channel (BEC) and the binary memoryless symmetric channel (BMSC) under any block rate-matched polar…
Erlang Model for Multi-type Data Flow
Liuquan Yao, Pei Yang, Zhichao Liu +3
With the development of information technology, requirements for data flow have become diverse. When multi-type data flow (MDF) is used, games, videos, calls, etc. are all requirem…
A Method to Reduce the Complexity of Computing the Complete Weight Distribution of Polar Codes
Zhichao Liu, Zhiming Ma, Guiying Yan
The code spectrum of polar codes is crucial to the performance of polar codes. Based on the lower-triangular affine group (LTA) of decreasing monomial codes and the one-variable de…
On the Weight Spectrum of Rate-Compatible Polar Codes
Zicheng Ye, Yuan Li, Zhichao Liu +4
The weight spectrum plays a crucial role in the performance of error-correcting codes. Despite substantial theoretical exploration of polar codes with mother code length, a framewo…
