PERBANDINGAN OSR (OVERSAMPLING RATIO) PADA PEMODELAN TEKNIK MODULASI SIGMA DELTA DAN Q-JOINT
Abstract
The purpose of this study was to optimize the performance of Broadbrand 4G to accommodate QoS (Quality of
Service) on the efficiency of frequency spectrum and linearity stability in the transmitter / receiver infrastructure. The
research method simulates a transmitter design that applies a sigma delta band-pass modulation and a Q-joint
quantization system. This modulation technique is the initial structure for RF transmitter design using the power
amplifier (SMPA) mode switch. The result achieved is the comparison of the OSR values in the Delta Sigma transmitter
simulation shows the greater the OSR value the wider the bandwidth.
