AVS-M is part seven of AVS standard, which is the second generation source coding standard of China. Because the system resource is limited in mobile platform compared with AVS P2, AVS-M has lower complexity, and is suitable for mobile-multimedia applications. The performance of AVS-M is close to H.264/AVC in the case of low rate bitstream. It is very important to increase the real-time encoding and...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H) which is required to operate under high mobility conditions resulting in significant Inter-Carrier Interference (ICI). Under these conditions, the conventional one-tap per subcarrier channel estimation and equalization is suboptimal since it does not account for ICI...
Fast Fourier Transform (FFT) is the most basic and essential part of Software Defined Radio (SDR). Therefore, designing regular, reconfigurable, modular and low hardware complexity FFT computation block is very important. A single FFT block should be configurable for varying length FFT computation and also for computation of different transforms like DCT, DST etc. In this paper, the authors analyze...
