Parallel Concatenated Block (PCB) codes are conventionally represented as high-rate codes with low error correcting capability. To form a reliable and outstanding code, this paper presents a modification on the structure of PCB codes, which is accomp

The video bitstream compressed by the efficient high efficiency video coding (HEVC) standard is extremely vulnerable to the channel error. For robust transmission of such compressed videos, techniques can be formed based on the specific characteristi

A high-performance polar code introduced as a product polar code can be constructed by concatenating two short length polar codes. The punctured structure of this code was achieved by puncturing one of its constituent codes. The constructed polar cod
