A two-block model of a digital corrector is proposed for linearization of an analog radio path with a nonlinear characteristic and frequency-dependent mismatch of the modulator quadrature channels. Using the stochastic gradient method and the recursive least squares method, the problem of identifying each block of a given model on the basis of once measured data is solved. A comparative analysis of systems with digital correction, implemented using two-block and one-block structures, is carried out.

带有模拟平方调制器的无线电线路线性化数字校正器的两块模型

提出了一种数字校正器的两模块模型，用于线性化具有非线性特性的模拟无线电路径和调制器正交通道的频率相关失配。使用随机梯度法和递推最小二乘法，解决了基于一次测量数据识别给定模型的每个块的问题。对使用两块和一个块结构实现的具有数字校正的系统进行了比较分析。
