一个真正SERVER PUSH的聊天室,很不错,C语言所写,最可惜的是已经被编译过了,但是界面全部被独立出来了的,可以自行更改,只是不能研究程序的内部结构…… (a real SERVER PUSH chat rooms, very good, C language written, it is most unfortunate that has been compiled, but the interface were all independent of and can make changes, but the procedures are not able to study the internal structure of ...)

说明: 6. 在三条径的瑞利信道中,对于OFDM:
(1) 请设计一种具体的导引辅助的信道估计方法,用Simulink进行仿真。画出比特信噪比与信道估计均方误差的关系曲线和比特信噪比与误码率的关系曲线。
(2) 设频率已同步,请设计OFDM一种具体的采用循环前缀进行时间同步方法,用Simulink进行仿真,画出比特信噪比与捕获概率的关系曲线。
(3) 设时间已同步,请设计OFDM一种具体的采用循环前缀进行频率同步方法,用Simulink进行仿真,画出比特信噪比与频率同步误差的关系曲线。(6. In the three-path Rayleigh channel, for OFDM:
(1) please design a specific navigation-assisted channel estimation method and use Simulink for simulation.The relation curves of bit signal-noise ratio and channel estimation mean square error and the relation curves of bit signal-noise ratio and bit error rate are drawn.
(2) if the frequency has been synchronized, please design a specific method of time synchronization using cyclic prefix in OFDM. Simulink is used for simulation to draw the relationship curve between bit-snr and acquisition probability.
(3) if time has been synchronized, please design a specific method of frequency synchronization using cyclic prefix in OFDM. Simulink is used for simulation to draw the relationship curve between bit signal-to-noise ratio and frequency synchronization error.)
