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 ofService) on the efficiency of frequency spectrum and linearity stability in the transmitter / receiver infrastructure. Theresearch method simulates a transmitter design that applies a sigma delta band-pass modulation and a Q-jointquantization system. This modulation technique is the initial structure for RF transmitter design using the poweramplifier (SMPA) mode switch. The result achieved is the comparison of the OSR values in the Delta Sigma transmittersimulation shows the greater the OSR value the wider the bandwidth.
