Software Defined Radio (SDR) is a computer based system that emulates the behavior of traditional radio systems by processing digitized radio signals. A SDR replaces the traditional fixed hardware radio with a system that may be reconfigured, both during operation to provide greater flexibility and by providing software upgrades to add new capabilities without requiring new hardware. Due to these powerful reasons, a wide range of radio applications like GSM, Bluetooth, GPS, Radar, GPRS, etc. can be implemented using SDR technology. In this paper, the global system of mobile communications (GSM) frequency hopping transmitter using SDR technology is designed and simulated with Matlab/Simulink. It has been implemented using 1-bit Continuously Variable Slope Delta- Modulation (CVSD) for speech coding, then channel coding using Block codes and Convolutional codes is designed. After that Diagonal Interleaver is used. Then BFSK modulation is designed. Finally BFSK modulation with Frequency Hopping is used which provide protection against eavesdropping and jamming. The performance analysis according to data rate of input and output signals is presented and discussed.
