当空间调制（sm）系统中每个符号含有3bits信息(即3bit/s/Hz的频谱利用率)时我们选择：4根发送天线，BPSK调制方式和2根发送天线，4QAM调制方式进行比较。(When the spatial modulation (sm) system, each symbol comprising 3bits information (i.e. 3bit/s/Hz spectral efficiency) when we choose: four transmitting antennas, BPSK modulation method and two transmission antennas, 4QAM modulation for comparison.)

matlab仿真源代码，AM源程序，用matlab运行(matlab simulation source code, AM source, using matlab to run)

三次样条曲线，可以根据不同条件进行选择，包括边界条件等(Cubic spline curve can be selected according to different conditions)

针对带时滞二阶振荡环节的系统传递函数,我们这里研究了,二阶振荡环节时间常数增大,对系统动态性能的影响,读者可以在程序上对时间常数进行修改,即可得出比较与区别.(brought against Delay second oscillation link system transfer function, we studied here, and the second time constant oscillation links increased, the dynamic properties of readers, the procedure for amending time constant can be obtained by comparison with distinction.)

Cognitive Radio / Cognitive Network System simulator in matlab source code. To Simulate Cognitive Radio System which is so effective that it can harvest more band-width in highly desired bands than is currently in use!
