MIMO信道容量的Matlab仿真程序,可以仿真出正确的图形(MIMO channel capacity of Matlab simulation program, can simulate the correct graphics)

利用m序列生成跳频序列并用于跳频通信，并给出误码率曲线(Use of m sequences generated hopping sequence and used for frequency hopping communications, and give the bit error rate curve)

鼠标拖到什么地方就显示这里的坐标，很有意思的程序。对于精确地显示很有作用(The mouse dragged into what place it is here that the coordinates, very interesting program. To accurately display the very useful)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)
