实验室的试验测量指出,当通道具有同比特率带宽近于相等的带宽和典型的有关相位延迟特性时,MSK 与 OKQPSK 调制方式有近乎相等误差率性能.为了在比较不同调制方式的性能时消除硬件质量不同引起的差异,设计与制造了高质量 MSK 与 OKQPSK 发射机和通用模型接收机。因此,调制方式的选择应主要考虑复杂性、对设备组合的敏感度和差分编码合适性,而不是误差率。
Laboratory experimental measurements point out that MSK and OKQPSK modulation have nearly equal error rate performance when the channel has nearly equal bandwidth and nearly the same phase delay characteristics of the same bitrate bandwidth. To eliminate the need to compare the performance of different modulation schemes Hardware quality differences caused by the difference, design and manufacture of high quality MSK and OKQPSK transmitter and universal model receiver. Therefore, the choice of modulation mode should mainly consider the complexity, sensitivity to the device combination and the suitability of differential coding, not the error rate.
