Abstract
In this paper, a comparative study of different digital predistortion models is presented in the scenario of a phased array transmitter with multi-channel time delay in the over-the-air (OTA) feedback loop-based structure. The performance for three classic volterra models with enhanced piecewise technique is compared. Experiment results indicated that all the models above can be applied to this scenario and achieve satisfactory linearization performance.
