Kertas kerja ini membincangkan model diskret yang cekap untuk penguat kuasa RF (PA) tak linear dengan kesan ingatan jangka panjang dan menganalisis ralatnya. Prosedur menukar isyarat dan sistem RF kepada domain diskret dijelaskan untuk model polinomial memori jalur asas diskret. Tidak seperti model polinomial ingatan ringkas sebelumnya, model diskret yang dicadangkan mempunyai dua frekuensi pensampelan berbeza: satu untuk sistem tak linear dengan kesan ingatan jangka panjang dan satu untuk isyarat input. Kaedah untuk memilih kekerapan pensampelan optimum untuk sistem dan kedalaman memori diskret dicadangkan untuk meminimumkan kepekaan sistem untuk gangguan data yang diukur. Fungsi kepekaan dua dimensi yang merupakan produk baki relatif dan nombor keadaan matriks ditakrifkan untuk masalah kuasa dua terkecil bagi model yang dicadangkan. Contoh dengan isyarat WiBro 3FA jalur lebar dan isyarat WCDMA 4FA untuk pemancar tak linear dibentangkan untuk menerangkan prosedur keseluruhan dan keberkesanan skim yang dicadangkan.

Abstract: This paper discusses an efficient discrete model for nonlinear RF power amplifier (PA) with long-term memory effects and analyzes its error. The procedure of converting RF signals and systems into a discrete domain is explained for a discrete baseband memory polynomial model. Unlike a previous simple memory polynomial model, the proposed discrete model has two different sampling frequencies: one for nonlinear system with long-term memory effects and one for input signal. A method to choose an optimal sampling frequency for the system and a discrete memory depth is proposed to minimize the sensitivity of the system for perturbation of the measured data. A two-dimensional sensitivity function which is a product of relative residual and matrix condition number is defined for least square problem of the proposed model. Examples with a wideband WiBro 3FA signal and a WCDMA 4FA signal for nonlinear transmitters are presented to describe the overall procedure and effectiveness of the proposed scheme.
