Delayed projection neural network for solving degenerate quadratic program

Yong Yang, Jing-wen Zhang
A delayed projection neural network model is presented for solving degenerate quadratic programming problem with general linear constraints. By constructing suitable Lyapunov functions, the proposed neural network is proved to be global convergent to the equilibrium points set. Compared with the existing...

Performance Analysis of Dual-Hop Multi-Relaying with Max-Mini Relay Selection over Composite Fading Channels

Wu Chia-Hao, An John F.
In dual-hop multi-relaying wireless systems, the non-closed form expression in log-normal probability distributions and high varying standard deviations makes it impossible to effectively execute performance analyses of outage probability and bit-error-rate (BER) performance levels; thus, an analysis...

A Promotion SAR Raw Data Compressing Algorithm Based on BAQ

Li Sun, Yuedong Zhang, Min Wang, Fufei Gu
BAQ algorithm is widely used in SAR raw data compressing, but SAR raw data does not perfectly submit to normal distribution in some cases. One of situation is fractional saturation of raw data. This paper proposes a promoted BAQ algorithm to compress SAR raw data by changing the quantization algorithm....

A New Data Transfer Scheme for eMMC Connected Subsystems

Deng Shulan
One of the issues in data transfer between host CPU and its eMMC connected subsystem is to determine when to send data from host to subsystem and when to receive data from subsystem to host with least CPU interference. The conventional approach to achieving data transfer synchronization is by polling,...
