在mW复合序列扩频(CS-SS)通信系统中,发射端和接收端都用到了沃尔什函数发生器,它在系统实现和同步中起重要作用。提出了一种新的沃尔什函数发生器算法,这种新的方法利用沃尔什函数的哈达马表示方法产生沃尔什函数,结构简单,实现灵活。由于采用同步时钟控制,生成的沃尔什函数具有很好的正交特性。 In the mW composite sequence spread spectrum (CS-SS) communication system, the Walsh function generator is used on both the transmitter and the receiver, which plays an important role in system implementation and synchronization. A new Walsh function generator algorithm is proposed. The new method uses the Hadamard representation of the Walsh function to generate the Walsh function, which has the advantages of simple structure and flexible implementation. Due to the use of synchronous clock control, the generated Walsh function has good orthogonality.
