A Baseband Digital Predistorter design is proposed in this paper for a UHF 8 MHz Power Amplifier (PA) for DVB-T transmitter. A Memory Polynomial (MP) model is considered for the PA characterization and its coefficients are estimated based on Least Square Estimation (LSE) algorithm. The Indirect Learning Architecture (ILA) approach is used to estimate the coefficients of the predistorter. Simulation...
This paper deals with Field Programmable Gate Array (FPGA) implementation design of a Predistorter real-time processing. The corresponding Baseband Digital Predistortion (DPD) is based on Memory Polynomial (MP) modelling of a UHF 8 MHz LDMOS Power Amplifier (PA). The PA MP model coefficients are estimated based on Least Square Estimation (LSE) algorithm. The proposed DPD design is using Look Up Table...
Low amplitude impulsive noise measurements have been carried out in the time domain on a vehicle power line network. These measurements were made on a stationary vehicle and the motor idling. The characteristics of the measured low amplitude pulses were studied in terms of amplitude, frequency, duration and time interval between successive pulses. Stochastic models based on mathematical distribution...
