This thesis investigates the design and implementation of wireless communication system
over the GNU Radio. Wireless applications are on the rise with advent of new devices, therefore
there is a need to transfer the hardware complexity to software. This development enables
software radio function with minimum hardware dependency. The purpose of this thesis is to
design a system that will transmit compressed data via Software Defined Radio (SDR). Some
parameters such as modulation scheme, bit rate can be changed to achieve the desired quality
of service. In this thesis GNU (GNU's not unix) radio is used while the hardware structure is
Universal Software Radio Peripheral (USRP). In order to accomplish the goal, a compression
technique called H264 (MPEG_4) encoding is applied for converting data into compressed
The encoder was implemented in C++ to get compressed data. After encoding, the
transmitter reads the compressed data and starts modulation. After modulation, the
transmitter put the packets into USRP and sends it to the receiver. Once packets are received
they are demodulated and then decoded to recover the original data.
