In this paper, we present framing and multiple-physical layer pipe (PLP) structures for layered division multiplexing (LDM)-based next generation terrestrial broadcasting systems. As a framing structure, single-layer frames and multi-layer frames can be simultaneously transmitted by a time division multiplexing (TDM) approach. In addition to a conventional multiple-PLP strategy, which is basically...
In this paper, we present a comparative study of the performance of the joint time of arrival/direction of arrival (TOA/DOA) estimation techniques - estimation of signal parameters via rotational invariance technique (ESPRIT), joint angle and delay estimation (JADE) and space-alternating generalised expectation maximisation (SAGE) - in the context of a strong multipaths model. We focus on a number...
H.264/AVC media stream transmission is an important application in wireless network, but wireless network is an open network, the media security must be considered. The encryption approach which is used commonly for encryption of H.263/MPEG-4 stream can not be used for H.264/AVC's directly, because the H.264/AVC stream data format is different from H.263/MPEG-4. Base on residual block spatial scrambling,...
