~The Major research area of Mao-Chao Lin is error-correction codes and its applications to communication system. Recent interesting results include：
1. Decoding of short block codes : We employ the advanced information of parity bits to increase the decoding speed of tree decoding. We also propose methods to significantly reduce the stack size.
2. PAPR Reduction : We employ deliberate bit flipping and error-correcting codes to relieve the PAPR problem in OFDM systems.
3. Raptor codes : We design Raptor codes with low decoding complexity.
