A new method, based on support vector machines (SVMs) and genetic algorithm (GA), is proposed for automatic Intra-Pulse modulation recognition (AIMR). In particular, the best feature subset from the combined pulse descriptor word (PDW) feature set and time-frequency feature set is optimized using genetic algorithm. Compared to the conventional decision-theoretic method, the method proposed avoids...
The hybrid architecture of content distribution network (CDN) and peer to peer (P2P) is promising in providing online streaming media services. It's convenient and low in cost to study the design space of hybrid streaming systems via simulation. In this paper, we designed a discrete-event simulator for hybrid CDN-P2P VoD systems. The simulator supports multiple switching strategies, different video...
This paper presents a floating-point fused multiply-add (FMA) unit with low-cost and low power techniques. To improve the performance, two single-precision operations can be performed concurrently with one double-precision datapath, which is very useful in multimedia and even scientific applications. Moreover, to reduce the additional area costs for supporting two single-precision operations in parallel,...
