OPQSK调制信号的载波相位/频率以及时间同步算法的实现与验证，很有使用价值(OPQSK modulated signal carrier phase/frequency and time synchronization algorithm and validation, very valuable)

Spread spectrum techniques can be very useful to overcome the communication problems like security and efficient usage of power. In this technique, the information signal to be transmitted is multiplied by the PN code (This is the general case and it can be any kind of sequence.),called spreading code signal. The signal which is obtained after the multiplication of PN code is called spread signal which is then transmitted.

本文讨论了航迹起始的概念, 综述了多种航述起始方法, 着重介绍了一种工程实用 的逻辑法, 最后对有关问题进行了讨论。(This paper introduces the concept of track initiation, summarized the various airlines starting method, introduces a practical The logic method, finally discusses related problems.)

In this paper, a dq model based on transformation theory for five-phase induction machines is presented. A detailed implementation of an indirect-type five-phase field-orientation control including the hysteresis-type pulsewidth modulation (PWM) current regulator is described. A method for continuous and disturbance-free operation of a five-phase field-orientedcontrolled induction motor drive with complete loss of one, two, or even three legs of the inverter or motor phases is described. A complete analysis and computer simulation of this control technique is included.
