正交失真 quadrature distortion
- 由模拟器件构成的宽带正交解调接收机会由于正交通道的幅相不一致性造成整个系统的失真,进而影响整个接收系统的性能。
The system distortion is inevitable in wide-band analog quadrature receiver because of the existing of amplitude and phase errors, the performance of receiver become worse. - 本文提出了一种用于正交频分复用(OFDM)系统中由大功率放大器引起的非线性失真的有效的数字自适应补偿方法。
The paper presents an efficient digital adaptive method compensating for nonlinear distortions caused by a high-power amplifier (HPA) in orthogonal frequency division multiplexing(OFDM) system.
