摘要

提出了一种新的简便的高斯最小移位键控(GMSK)差分检测器。新的检测器包含了众所周知的两位差分检测器作为特例。仿真结果表明,在AWGN信道中,该检测器的性能比2位差分检测器至少提高1 dB,比传统的1位差分检测器的性能好得多。此外,在具有快速瑞利衰落和/或共信道干扰的信道中,可以观察到误差层的显著改善。

A new differential detector for GMSK
A new and simple differential detector is presented for Gaussian minimum shift keying (GMSK). The new detector includes the well-known two-bit differential detector as a special case. Simulation results show that the performance of the new detector is at least 1 dB better than the two-bit differential detector, and much better than the conventional one-bit differential detector in AWGN channels. Also, noticeable improvements on error floors are observed in channels with fast Rayleigh fading and/or cochannel interference.
