说明： 逆变器将直流电转化为交流电，若直流电压较低，则通过交流变压器升压，即得到标准交流电压和频率。对大容量的逆变器，由于直流母线电压较高，交流输出一般不需要变压器升压即能达到220V，在中、小容量的逆变器中，由于直流电压较低，如12V、24V，就必须设计升压电路。(The inverter converts DC into AC. if the DC voltage is low, the standard AC voltage and frequency can be obtained by boosting the voltage through the AC transformer. For large capacity inverters, because of the high DC bus voltage, the AC output can reach 220V without transformer boosting. In medium and small capacity inverters, because of the low DC voltage, such as 12V and 24V, the boost circuit must be designed.)

TSCMA
说明： 针对信道均衡盲均衡常模算法的初始化问题，不同于普遍的中心抽头初始化，移动抽头可以避免收敛到局部极小值。(For the initialization problem of channel equalization blind equalization constant modulus algorithm, unlike the common centralized tap initialization, mobile tap can avoid convergence to local minimum.)
