Circular Buffer Rate-Matched Polar Codes
Mostafa El-Khamy, Hsien-Ping Lin, Jungwon Lee +1
A practical rate-matching system for constructing rate-compatible polar codes is proposed. The proposed polar code circular buffer rate-matching is suitable for transmissions on co…
Binary Polar Codes are Optimized Codes for Bitwise Multistage Decoding
Mostafa El-Khamy, Hsien-Ping Lin, Jungwon Lee
Polar codes are considered the latest major breakthrough in coding theory. Polar codes were introduced by Arıkan in 2008. In this letter, we show that the binary polar codes are th…
Rate-Compatible Polar Codes for Wireless Channels
Mostafa El-Khamy, Hsien-Ping Lin, Jungwon Lee +2
A design of rate-compatible polar codes suitable for HARQ communications is proposed in this paper. An important feature of the proposed design is that the puncturing order is chos…
Relaxed Polar Codes
Mostafa El-Khamy, Hessam Mahdavifar, Gennady Feygin +2

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding
Hessam Mahdavifar, Mostafa El-Khamy, Jungwon Lee +1
We consider the problem of polar coding for transmission over -user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, whil…
Performance Limits and Practical Decoding of Interleaved Reed-Solomon Polar Concatenated Codes
Hessam Mahdavifar, Mostafa El-Khamy, Jungwon Lee +1
A scheme for concatenating the recently invented polar codes with non-binary MDS codes, as Reed-Solomon codes, is considered. By concatenating binary polar codes with interleaved R…
