说明：  基于子空间投影的 CSMG 波束形成算法，是一种将子空间投影与波束形成技术相 结合的抗干扰方法。该方法首先构造干扰子空间的正交补空间，再将天线阵列接收到的空时信号矢量向其投影，然后对投影后的输出信号采用具有严格约束最小功率的抽样矩阵梯度（CSMG）算法，在固定方向上进行波束形成，最后捕获、定位及解算出每个波束得到的无干扰数据等，可以有效地抑制干扰信号，同时又可以更好的保留期望信号。(The algorithm of the CSMG beamforming based on subspace projection, which is a combination of the Subspace projection and beam forming technology. Firstly, the data vector received by antenna array is projected onto the interference subspace, which is orthogonal to interference subspace for achieving interference suppression. And then, by using the method of the strictly constrained minimum power sampling matrix gradient(CSMG), after the projection of the subspace, the signal is beamformed in a fixed direction. Finally, for jammer-free data of each beam achieved to capture, locate, solute and so on. The ability of the suppress interference by this method, which can be more effectively, and keep the desired signal better.)

说明：  bpsk调制仿真，可直接用 1、数字调制方法 数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。 数字信号的传输方式分为基带传输和带通传输。然而，实际中的大多数信道（如）无线信道具有丰富的低频分量。为了使数字信号在带通信道中传输，必须用数字基带信号对载波进行调制，以使信号与信道的特性相匹配。(1, digital modulation method Digital modulation is the transfer of the spectrum of a digital baseband signal to a high frequency to form a bandpass signal suitable for transmission in the channel. The basic digital modulation methods are amplitude keying (ASK), frequency shift keying (FSK), absolute phase shift keying (PSK), and relative (differential) phase shift keying (DPSK). At the receiving end, the digital baseband signal can be restored by using dry demodulation or non-coherent demodulation. Digital signal transmission methods are divided into baseband transmission and bandpass transmission. However, most channels in practice, such as wireless channels, have rich low frequency components. In order for a digital signal to be transmitted in a band channel, the carrier must be modulated with a digital baseband signal to match the signal to the characteristics of the channel.)
