摘要

直接转换接收机(DCR)接收质量的提高需要考虑和补偿正交下转换的缺陷。直流偏置和I/ q不平衡属于这一类。本文综述了两种相对简单的补偿方法的实验估计。能源效率和计算复杂性估计也包括在工作中。

Experimental investigation of quadrature downconversion impairments estimation and compensation methods to the M-QAM signals

Quadrature downconversion impairments should be taken into account and compensated to the increasing of the Direct Conversion Receiver (DCR) reception quality. DC-offset and I/Q-imbalance are fitted into this group. Experimental estimation of two relatively simple compensation methods for the indicated drawbacks is reviewed in the paper. Energy efficiency and computational complexity estimation are also including into the work.
