Özet:

In this thesis, for the sake of increasing spectral efficiency, the use of Dirty Paper Coding for the spectral co-existence of primary and secondary users in slow Rayleigh fading 2x2 cognitive radio channel through asymmetric transmitter cooperation has been investigated. It is assumed that the primary channel is SISO and the secondary is a MISO channel, adopting spectrum overlay approach over a generalised cognitive radio channel. Namely, in a 2x2 SISO-MISO network, the spectrally active regions of the radio spectrum are also used in addition to the use of inactive parts when available. In this context, a dirty paper coding method based on spatial modulation is proposed and its use with space-time block coding is investigated through software simulation, subject to coexistence-conditions.
