Based on fractional sampling method, a new super - exponential iteration decision feedback blind equalization algorithm for severely nonlinear phase distortion channels was proposed
因此針對嚴重頻率衰落和非線性相位失真通道,提出了一種分數采樣的混合盲均衡演算法,並獲得了較快的收斂速度和較小的剩餘均方誤差。The predistortion, which aims at compensating for the nonlinear distortion caused by the power amplifier, has a good performance in eliminating the nonlinear distortion of am / am & am / pm, improving the aci and spectrum efficiency
預失真技術是針對射頻功率放大器非線性而提出的一種補償技術,可以有效消除由非線性造成的傳輸信號的幅度和相位失真,降低信號鄰道干擾( aci ) ,提高頻譜利用效率。Signal distortion includes three kinds of distortion : frequency, phase and waveform
信號的失真分為頻率失真、相位失真和波形失真等三種。When signals pass high power amplifier, they would be distorted in amplitude and phase, leading to spectrum spread and distortion of in - band signals, both of which would weaken performance of the whole system in turn
在無線通信中,信號在通過高功率放大器時會產生幅度和相位失真,造成頻譜擴展以及帶內信號畸變,導致整個系統性能的降低。Considering the nonlinear difference of the gain and phase characteristic in solid state power amplifier ( sspa ), a parallel but imbalanced predistorting adjuster is used and the hardware cost can be reduced
考慮到固態功率放大器( sspa )幅度和相位非線性特性的差異,該系統採用幅度和相位不平衡調節的射頻預失真結構,降低了硬體成本。Influence of frequency and wave distortion on the verification of phasemeter
