主　　题：polar code rate compatible hybrid automatic re-transmission request polar coding/decoding 

摘      要：Polar coding are the first class of provable capacity-achieving coding techniques for a wide range of *** an ideal recursive structure and many elegant mathematical properties,polar codes are inherently implemented with low complexity encoding and decoding *** the block length of the original polar construction is limited to powers of two,rate-compatible polar codes(RCPC)are presented to meet the flexible length/rate transmission requirements in *** RCPC codes are well-conditioned to combine with the hybrid automatic repeat request(HARQ)system,providing high throughput efficiency and such RCPC-HAPQ scheme is commonly used in delay-insensitive communication *** paper first gives a survey of both the classical and state-of-the-art encoding/decoding algorithms for polar *** the RCPC construction methods are discussed,including the puncturing,shortening,multi-kernel construction,***,we investigate several RCPC-HARQ jointly design systems and discuss their encoding gain and re-transmission diversity gain.
