Context adaptive binary arithmetic coding (CABAC) is the entropy coding tool applied in the latest video coding standard, High Efficiency Video Coding (H.265/HEVC). CABAC achieves high coding efficiency but involves the bin-to-bin data dependency of Binary Arithmetic Encoder (BAE). This paper proposes a range updating structure with pre-bitwise-NOT (PBN) operation to shorten the critical paths in...
When communicating at high-speed environment such as high-speed rail, the signals may encounter fast fading due to the terrain changes. In such communication environment, signal prediction can help improve the system throughput and reduce packet loss. In this paper, we propose a prediction mechanism called Window Weight Moving Average (WWMA) to predict the signal strength. We also analyze the real...
