笔者长期从事移动通信系统的无线链路调制与解调物理层实现方面的工作，所以在这里我们给出语音或者业务信道链路过程的交织与解交织的DSP实现方法。需要说明的是：这是针对定点DSP、C55xx的编程实现方法，希望对读者有益。-The author has long been engaged in mobile communication systems wireless link physical layer modulation and demodulation realize the work, so here we give voice channel link or business process interwoven with deinterleave realize the DSP approach. It should be noted that: This is for fixed-point DSP, C55xx programming realize, and I hope that useful to readers.
