符号采样速率对POLAR发信机相位调制精度的影响

The Effect of Symbol Sampling Rate on Phase Modulation Accuracy in Polar Transmitter

介绍了POLAR发信机的基本原理、特点和基于锁相环的相位调制技术。分析了相位频率变换中,符号采样速率对相位调制精度的影响,并通过仿真说明了发信机误差矢量幅度随采样速率的变化规律。

First introduces the polar transmitter principles and phase modulation based on phase lock loop.Then analyzes the symbol sampling effect on phase modulation accuracy.Finally,a simulation is show to demonstrate this effect on EVM.
