Abstract
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.
