摘要
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。
Walsh function generator is used both in the transmitting terminal and in the receiving end in a mW composite sequence spread spectrum communication system. It is very important to the implementation and synchronization of the system. This paper proposes a new arithmetic of walsh function generator (WFG). The new method uses hadamard representation of walsh function to generate synchronous clock, this WFG has good orthogonal characteristics. walsh function, walsh function generator, hadamard matrix, CPLD
