This article proposes, a reconfigurable FEC system based on Reed-Solomon codec for DVB and WiMax networks. The proposed architecture implements various programmable primitive polynomials. A lot of VLSI implementations have been described in literature. This paper introduces a highly parametrical RS-coder-decoder on FPGAs. The implementation, written in a(More)
Motion estimation in video coding standards, such as H.264/AVC, is considered to be the most time-consuming encoding module. Motion estimation is generally performed on a 16x16 block, although in H.264/AVC, 7 different block sizes (16x16, 16x8, 8x16, 8x8, 8x4, 4x8 and 4x4) are allowed. The aim of this paper is to optimise the implementation of the motion(More)
The H.264/AVC Advanced Video Coding standard (AVC) is poised to enable a wide range of applications. However, its increased complexity creates a big challenge for efficient software implementations. This work develops and optimises the H.264/AVC video decoder level two on the TMS320C6416 Digital Signal Processor (DSP) for video conference applications. In(More)
The coding gain of the H.264/AVC video encoder mainly comes from the new incorporated prediction tools. However, their enormous computation and ultrahigh memory bandwidth are the penalties. In this paper we present an approach supporting efficient data reuse process to avoid unnecessary memory accesses and redundant motion estimation computations combined(More)
This article proposes an adaptive coded modulation (ACM) with multi-levels qualities of service analysis, which can be used to perform physical layer functions in software radio receivers for beyond third generation systems. ACM approche employs multiple coding and modulation schemes in order to adapt instantaneously spectral efficiency to the(More)
