说明：  使用改进的Nyquist脉冲实现OFDM信号的PAPR抑制(Achieved using the modified Nyquist pulse inhibition of OFDM signal PAPR)

The standard optimum Kalman filter demands complete knowledge of the system parameters, the input forcing functions, and the noise statistics. Several adaptive methods have already been devised to obtain the unknown information using the measurements and the filter residuals.(The optimum standard Kalman filter demand 's complete knowledge of the system parameters. the input forcing functions. and the noise statistics.

[sigma,mu,A]=mygaussfit(x,y) [sigma,mu,A]=mygaussfit(x,y,h) this function is doing fit to the function y=A * exp( -(x-mu)^2 / (2*sigma^2) )

演示椭圆的曲率圆的动画。该程序演示了椭圆各点的曲率变化及相应的曲率圆圆心的轨迹。(Demonstration of the curvature ellipse circle animation. The program demonstrates the various points of the curvature of the ellipse and the corresponding changes in the curvature of the round locus of the center.)

An ad-hoc network with a sender, a destination and a third station act- ing as a relay is analysed. The channels are modelled containing thermal noise, Rayleigh fading and path loss. Di® erent combining methods and di- versity protocols are compared. The amplify and forward protocol shows a better performance than the decode and forward protocol, unless an error correcting code is simulated. To combine the incoming signals the chan- nel quality should be estimated as well as possible. Information about the average quality shows nice bene¯ ts, and a rough approximation about the variation of the channel quality increases the performance even more. What- ever combination of diversity protocol and combining method is used second level diversity is observed. The relative distances between the relay and the stations has a large e® ect on the performance.
