The second generation Audio-video Coding Standard (AVS2) is the latest video standard currently under the development of Audio-video Coding Standard (AVS) Workgroup of China for achieving higher coding efficiency than previous (AVS1). In intra luminance prediction of AVS2, the AVS2 video encoder has to compute the rate-distortion optimization (RDO) of 9 selected candidate prediction modes in order...
It is well known that the short cycles in Tanner Graph (TG) greatly impact on the iterative decoding performance of low density parity check (LDPC) codes. In previous literature two methods can be found for detecting such short cycles. This paper presents an improved version of previous Jun Fan's method, which is based on combinational analysis and enumeration of the check matrix patterns caused by...
