(九宫问题)在一个3×3的九宫中有1-8这8个数及一个空格随机的摆放在其中的格子里,如图1-1所示。现在要求实现这个问题:将该九宫格调整为如图1-1右图所示的形式。调整的规则是:每次只能将与空格(上、下、或左、右)相邻的一个数字平移到空格中。试编程实现这一问题的求解。((Nine-palace issues) in a 3 × 3 of the Nine-palace are 1-8 this 8 random number and the placing of a space in which the cell house, as shown in Figure 1-1. Now required to achieve this issue: the squares adjustment for the right as shown in Figure 1-1 form. Adjustment of the rules: each can only be with the spaces (upper and lower, or left, right) adjacent to a digital flat space. Test Programming to solve this problem.)

在三条径的瑞利信道中,对于直接序列扩频:
(1) 请设计DS-CDMA一种具体的码分导引辅助的信道估计方法,接收机分别采用等均益合并、最大比合并。用Simulink进行仿真,测量BPSK的误码率性能,画出比特信噪比与信道估计均方误差的关系曲线,画出比特信噪比与误码率的关系曲线,请解释在误码率为0.01时,两种合并方式所表现的不同的物理意义。
(2) 设频率已经同步,请设计DS-CDMA一种具体的单停顿滑动相关时间同步方法,用Simulink进行仿真(自己编写代码S-Function方式),分析所设计方案的时间同步精度,画出比特信噪比与捕获概率的关系曲线。
(3) 设时间已经同步,请设计DS-CDMA一种具体的频率方法,用Simulink进行仿真(自己编写代码S-Function方式),画出比特信噪比与频率同步误差的关系曲线。

导引辅助的信道估计
说明: 在单径瑞利信道中,设计一种时分的导引辅助的信道估计方法,用Simulink和m语言进行仿真,测量BPSK的误码率性能,画出比特信噪比与误码率的关系曲线,并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)
