frequency modulation distortion

基本解释

The fundamentals of LFM(linear frequency modulation) signals, waveform parameter design, system control, quality analysis and pre-distortion calibration are discussed in this paper.
本文討論了線性調頻信號的基本理論，研究了信號蓡數設計、系統控制、性能分析與預失真校正。
In the multi-carrier modulation of DMT communication system, both time domain and frequency domain equalizers are used to compensate for the magnitude and phase distortion within each subchannel.
