Abstract: This paper proposed a complexity-reduced band-limited memory polynomial model. It is achieved by forward compensating the modeling error caused by the band-limited memory polynomial with low order band-limiting filter,which reduces the required order of band-limiting filter and improves the accuracy significantly. A class-AB GaN PA excited by a 60MHz bandwidth orthogonal frequency division multiplexing (OFDM) signal was tested to validate this approach. Experimental results presents that the new model has much lower complexity and higher accuracy.
