viterbi simulation K = 7 in bpsk modulation

In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased

mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)
