POLAR CODE CONSTRUCTION AND CONFIGURATION FOR BLOCK-CODE-BASED SHAPING

Abstract

Certain aspects of the present disclosure provide techniques for Polar code construction and configuration for block-code-based shaping. An example method includes identifying a set of information bits for transmission, generating a set of log likelihood ratios (LLRs) corresponding to the set of information bits, segmenting the set of LLRs into a plurality of shaping blocks based, at least in part, on a shaping block length for the plurality of shaping blocks, decoding, according to a shaping code rate, the plurality of shaping blocks using a polar code to obtain a sequence of shaping bits, wherein the polar code used to decode the plurality of shaping blocks depends on the shaping code rate and the shaping block length, generating a sequence of shaped symbols from the sequence of shaping bits, transmitting the sequence of shaped symbols to a receiving device.
