摘　　要：介绍基于TI的TMS320VC5510 DSP(以下简称5510)和CML微电子的CMX981芯片组合实现π/4-DQPSK基带处理的方法。系统中5510除实现基带信号编解码外,利用其灵活的多通道缓冲串口(McBSP)控制CMX981多功能基带处理器的各种工作模式及快速数据收发。实验测试结果表明,5510和CMX981组合能很好地实现π/4-DQPSK基带处理,同时可大幅降低系统功耗。The realization of π/4-DQPSK baseband processing based on TMS320VC5510 DSP of TI and CMX981 of CML is introduced. Except for implementation encoding and decoding for baseband signal, the 5510 is also flexible control the baseband processor CMX981 in the data sent and received with use of McBSP. The experiments indicate that the combination of 5510 and CMX981 can realize π/4-DQPSK baseband processing. At same time, low power for the system is available.
