Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in

Using weighted model nodes in the network strength and weight are power law distribution, HARQ throughput analysis of the system, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.

HARQ throughput analysis of the system, The commonly used digital signal modulation based on artificial neural network, Using matlab to calculate the Mahalanobis distance for the image.

采用FPGA（现场可编程门序列）编写VHDL语言设计多路同步脉冲发生器，对信号进行分频处理，实现四路信号相位相差T/16和T/8的延迟相位输出，实现的四路脉冲与传统的脉冲同步器不同，它具有高集成度，高通用性，容易调整和高可靠性等特点。(Using FPGA (field programmable gate sequence) to write VHDL language to design multi-channel synchronous pulse generator, to divide
