PENGUKURAN UNJUK KERJA MODULASI GMSK PADA SOFTWARE-DEFINED RADIO PLATFORM
Abstract: This paper addresses
performance measurement of Gaussian Minimum Shift Keying (GMSK) modulation
which is implemented on Software-Defined Radio (SDR) platform using Universal
Software Radio Peripheral (USRP) from GNU Radio. GMSK modulation is very
popular and is adopted as GSM cellular phone modulation standard. The results of this research can be used as
basic concept in developing wireless communication system based on SDR
technology which is needed in Next-Generation Networks (NGN). The GMSK
performance is measured in terms of Packet Error Rate (PER) with several of
Eb/No, bit rate, modulation frequency, payload size, and gain values. Based on
this research, the lowest PER can be achieved by setting Eb/No value equal to
20 dB, optimum bit rate = 256 kbps, BT 0.25, optimum payload size = 4092 bytes,
and optimum gain equal to 100.
