试说明卷积编解码的工作原理。 请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编解码全部自己编写代码(S-Function方式)，在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。 (Description Convolutional codec test works. Please use Simulink simulation of convolutional coding and Viterbi decoding method used to decode, which codec to prepare all their own code (S-Function mode), in the AWGN channel, drawn-noise ratio and bit error rate curve.)

Incremental Conductance: In the incremental conductance algorithm, we find the derivative of PV output power with respect to output voltage. The dP/dV is evaluated and the algorithm keeps checking this value and changes the duty cycle such that dP/dV=- I/V = 0. This is the point at which maximum power is transferred. If dP/dV is greater than zero, it means the PV is operating to the left of the MPP. If dP/dV is less than zero, it means the PV is operating to the right of the MPP. This method holds an advantage over the perturb and observe method since it is fast and does not oscillate around MPP. However, the method could experience instability due the involvement of the derivative.
