Abstract
The implementation of cognitive radios is widely proposed through the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation. In the special case of cognitive radios however, the OFDM modulation scheme cannot simply be implemented without modification due to the huge change in the basic laws of the transmission paradigm. The main reason behind this is that the modulation scheme can no longer assume the contiguousness of its band as well as the interference that may be caused by the cognitive radio users operating in such close proximity to the licensed users. The research presented in this thesis namely identified two areas of cognitive radio which addressed these issues. These were the power loading and channel estimation areas.
