二相相移键控（BPSK）调制解调过程的MATLAB仿真实现。ASK、FSK、PSK这三种数字调制方式在抗干扰噪声能力和信号频谱利用率等方面，以相干PSK的性能最好，目前已在中、高速传输数据时得到广泛应用。(Binary phase shift keying (BPSK) modulation and demodulation process, MATLAB Simulation. ASK, FSK, PSK modulation in the three digital noise interference and signal spectrum efficiency, etc., to the best performance of coherent PSK, is now in the middle and high-speed transmission data are widely used.)

针对多目标测控问题，提出了一种实用的利用基于圆阵的数字波束形成技术来实现目标跟踪的系统。在系统实际工作于噪声和干扰环境中时，为避免计算梯度时可能出现的数值突变，提出了一种修正的梯度跟踪自适应算法，可靠地实现了权值更新，并对各阵元输出进行加权合并，以获得最大信号输出，同时实现对目标方位角和俯仰角的自动捕获和跟踪，且跟踪迅速、正确、稳定。仿真结果表明了所提出的方案的正确性。(Monitoring and control for multi-objective problem, a practical circular array-based digital beam forming technology to achieve target tracking system. Practical work in the system noise and interference in the environment is investigated in order to avoid calculate the gradient values may be mutations present a modified gradient tracking adaptive algorithms, reliably achieve the right value update, and the output of the array weighted combined to obtain maximum signal output, while achieving the target azimuth and elevation of the automatic capture and tracking, and tracking fast, accurate and stable. Simulation results show that the proposed scheme is correct.)
