AN IMPROVED LUT BASED PREDISTORTION METHOD FOR HPA WITH MEMORY EFFECTS IN WCDMA SYSTEMS

摘要：

In this paper, we focus on the 2D LUT (2- dimension look-up table) techniques for the mitigation of HPAs’ (High Power Amplifiers’) memory effects when transmitting WCDMA wideband signal. On the basis of the previous method, an improved two-dimensional LUT indexing method for HPA predistortion with memory is proposed. Simulation and experimental results show that the proposed method has more effective predistortion capabilities compared with the previous method.
