Abstract
General polar codes are disclosed that encode symbols of a q-ary alphabet, where q≥2. Systems and methods are also disclosed for performing code rate matching when using general polar codes. In one embodiment, a method performed at a transmitter includes receiving a plurality of bits at a polar encoder. The plurality of bits represent a plurality of q-ary symbols, where q>2. The method further includes encoding the plurality of bits using the polar encoder to generate a codeword of q-ary symbols represented by bits. The method further includes puncturing the codeword according to a puncturing pattern to obtain a punctured codeword having a reduced bit length.
