ABSTRACT
The aim of this thesis is to design and implement a software defined radio based wireless
communication system. Software defined radio is a feasible solution for reconfigurable
radios, which can perform different functions at different times on the same hardware.
The baseband section of a wireless communication system is first simulated and then implemented
in hardware. The performance of the baseband transmitter is analyzed using
constellation and eye diagrams for different modulation techniques and different signal-tonoise
ratios, while considering an additive white Guassian noise channel. The performance
of the receiver is analyzed by comparing the input and output waveforms. The performance
of the system in real time is also analyzed by implementing the system in hardware using
Xilinx Spartan 2E field programmable gate array. A comparison of the simulation results
with the results obtained from implementing the system on Spartan 2E hardware is presented
and discussed. It is shown that the simulation results and experimental results are
similar.
