本文讨论了一种全数字GMSK基带调制解调器的设计和实现。根据GMSK调制技术的特点,提出一种基于TMS320C5509的GMSK波形存储调制,有效地降低了设计的复杂度,采用多电平判决实现解调,提出了理论依据和实现方案,给出了实验流程,并给出了验证结果。

In this paper, the design and implementation of a GMSK base band digital modem are discussed. A type of Gaussian Filtered Minimum Shift Keying waveform storage modulation base on TMS320C5509 is manifested, according to the feature of gmsk modulation technology. It effectively reduces the complexity of the design. Demodulation is realized by method of discrimination detection and multilevel decision. The theoretical basis and implementation scheme are presented, as well as the result of the verification.
