PENERAPAN FITUR ADAPTIVE MULTI RATE (AMR) PADA JARINGAN GSM
Abstract: Adaptive Mutlirate
(AMR) is a feature that plays an important role in the efficiency of use of
cell/voice channels and GSM networks in overall and it can improve sound
quality dynamically based on actual measurements (real time) between Mobile
Station (MS) and Base Transmitter Station (BTS). Resources used as analytical
parameters are SQI (Speech Quality Index), MOS (Mean Opinion Score) and the
sound quality on the network without and with AMR. Measurements using Test
Equipment Mobile System (TEMS) while locking devices to the single channel and
comparing them between the two types of network. Based on test results it is
obtained that with voice channels with AMR can increase the value of SQI
approximately 40% for fullrate channels and about 60% for half-rate channels
producing a remarkable (excellent) level, with research and further measuring
it is expected to produce better and more perfect sound quality.
