recently, a novel switch architecture is proposed to provide more scalable and lower delay service for the internet applications. But the structure is blocking and based on packet dividing. It causes serious performance degradation for most variable-sized packet switch application. In this paper, a new network code scheme is proposed to improve the packet loss performance of a two stage load-balanced...
Based on the high peak to average power ratio of orthogonal frequency division multiplexing systems, several methods of reducing the peak to average power ratio were analyzed. Then a method based on Golay complementary sequences was proposed to realize the low peak to average power ratio. The high peak to average power ratio sequences were encoded into Golay complementary sequences, peak to average...
Computer wargame system presents a new convenient and efficient method to simulate and research war, which realizes the computerization from the traditional manual wargame map to the digital wargame map. And exact operational geographic information becomes very important while the operational director making the game decisions. The paper learns from the mature raster data coding technique of GIS and...
For the floorplan optimization problem, a hybrid algorithm based on simulated annealing and genetic algorithm was presented. And a kind of bistructure coding was applied, which was different from the traditional method, including the module code and variable code. The B*-Tree representation [1] was embedded in floorplan, which is an efficient, flexible representation. From the theoretical analysis,...
