| 摘 要： | 针对当前频率资源紧缺的现状,提高频谱利用率已成为通信技术研究的重要目标,而EBPSK调制可提高频谱利用率。讨论了如何利用Simulink进行EBPSK-MODEM系统仿真与研究,给出了具体的仿真模型,并利用该模型得到了系统在不同DAC和ADC采样率及量化位数时的解调性能。仿真结果表明,在DAC和ADC的有限数据转换精度对于EBPSK-MODEM解调性能的影响中,采样率要比量化位数明显得多。这对于硬件实现很有参考价值。

| Abstract: | Aiming at the shortage of frequency resources,spectral efficiency has become an important goal of communication research,and the EBPSK modulation is able to improve spectral efficiency.It was discussed how to use the Simulink to simulate and research an EBPSK-MODEM system,and a specific simulation model was given with which the demodulation performance under various sampling rates and quantization bits of DAC and ADC was obtained.Simulation results show that in the affect caused by finite conversion accuracies of DAC and ADC for the demodulation performance of EBPSK-MODEM,the sampling rate is much more significant than the quantization bits.This is useful for the hardware implementation. |
