Memory model is commonly used as the signal bandwidth gets wider, such as in WCDMA, mobile WiMAX and 3GPP LTE and LTE-Advanced (up to 100 MHz bandwidth, 5 component carriers of carrier aggregation ). For wider bandwidth, power amplifiers begin to exhibit memory effects. This is especially true for those high power amplifiers used in wireless. Search ACM Digital Library. Search Search.

This paper proposes a robust model for the accurate behavioral modeling and digital predistortion (DPD) of wideband radio-frequency power amplifiers (PAs). It is constructed using a complexity-reduced generalized memory polynomial (MP) (GMP) (CR-GMP) connected with a nonlinear memory effect (NME) subblock in parallel.

For wider bandwidth, power amplifiers begin to exhibit memory effects. This is especially true for those high power amplifiers used in wireless.
Different linearization techniques have been proposed to linearize Power Amplifiers (PAs) and improve the PA efficiency for non-constant envelope modulation schemes. Among all the linearization techniques, Digital Predistortion (DPD) is one of the most cost effective. For wider bandwidth applications, PA memory effects can no longer be ignored. Therefore in order to achieve a higher ....

Sep 18, 2006 · Conventional radio-frequency (RF) power amplifiers operating with wideband signals, such as wideband code-division multiple access (WCDMA) in the Universal Mobile Telecommunications System (UMTS) must be backed off considerably from their peak power level in order to control out-of-band spurious emissions, also known as “spectral regrowth.” Adapting these amplifiers to wideband operation .... The Generalized Memory Polynomial (GMP) model is one of the most commonly used in Digital Predistortion (DPD) to compensate for the nonlinearities and memory effects of Power Amplifiers (PAs)..
