Venue: Teaching Building 404（海韵教学楼404）

Abstract:

Low-density parity-check (LDPC) codes have been shown to accomplish error-correction capabilities approaching the Shannon's limits. They have been applied to/proposed for use in many wireless and wired standards. In this talk, we review the characteristics of LDPC codes and factors affecting their performance. In particular, we give an example on the design of LDPC decoders with low complexity, high throughput and very low error rate. Next, we present some results on polar codes, a new type of codes that have been proven theoretically to achieve Shannon's limits asymptotically. Finally, we present the challenges of LDPC codes and polar codes.
