CABAC is the entropy coding method adopted in H.264/AVC main profile. RDO is the mode decision method commended by JVT, which can improve the performance of encoder markedly. However, the computation complexity of video encoding increases drastically. In this paper, we propose a novel fast intra-mode decision algorithm for H.264, based on transform-domain bit-rate estimation technique, using the estimated...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
Several questions related to the complexity of communication over channels with noise are addressed. We compare some of our results to wellknown results in information theory. In particular we compare the following two problems. Assuming that the communication channel between two processors P1 and P2 makes an error with probability ε≫0, the identification problem is to determine whether P1 and P2...
