YZU professor develops a decoding algorithms of polar codes for 5G mobile communications

In response to the global trend of academic research in industrialization, Yuan Ze University has actively spread its energy of research and development (R&D) to the industry in recent years. In addition to encouraging innovative research by teachers and students, it also promotes practical teaching methods and international accreditation.

Professor Cheng-Hung Lin from the Department of Electrical Engineering proposed a "layer operation stop method for belief propagation (BP) decoding of polar codes, "which can be used in the current fifth-generation mobile technologies (5G). The numerical detection mechanism of the probability to detect and stop computing the higher probability can reduce the quantity of computation, the calculation time, and the chip's power consumption. This patented technology was awarded the Silver Medal in the 2022 Taiwan Innotech Expo Invention Competition.
