PARITY-CHECK-CONCATENATED POLAR ENCODER - UNIV INDUSTRY FOUNDATION UIF YONSEI UNIV

Title:

PARITY-CHECK-CONCATENATED POLAR ENCODER

Document Type and Number:

WIPO Patent Application WO/2019/022334

Kind Code:

A1

Abstract:

Provided is a parity-check-concatenated polar encoder. The parity-check-concatenated polar encoder may comprise an outer encoder and a polar encoder concatenated to the outer encoder. The outer encoder may be configured to receive m information bits and provide the m information bits and r parity check bits as output. The polar encoder may be configured to receive, as input, the m information bits and the r parity check bits provided from the outer encoder and n bits including [n-(m+r)] frozen bits provided from selected bit indices and provide n output bits. Bit indices and bit values for the r parity check bits, which are output together with the m information bits by means of the outer encoder, may be set such that corresponding input vector(s) are not input into the polar encoder as possible, so that any encoded vector(s) having a minimum hamming weight (MHW) among encoded vectors that can theoretically be output from the polar encoder is(are) not actually output.
