· Contributions in the Thesis: This research proposes highly efficient and reliable spectrum sensing techniques for future generation cognitive radio networks (CRNs). In this research, first, the novel edge detection algorithms based on continuous wavelet transform and discrete wavelet transform has been developed for wideband CRNs. This research, also investigates the spectrum sensing in cooperative CRNs, where optimal log likelihood ratio based hard-soft combing is proposed to improve the overall detection probability with less sensing overhead. Here, novel weight vector estimation is obtained using trust factor, reporting channel SNR and sensing channel SNR. A novel spectrum sensing scheme for multiuser multiple-input-multiple-output cooperative cognitive radio networks are also studied and a MAC layer decision confidence algorithm for the selection of the number of sensing antennas at FC is proposed. This research also aims the realization/experimental studies on Energy/Eigenvalue based spectrum sensing algorithm using NI USRP 2942R hardware devices in OFDM in order to demonstrate its feasibility in real time communication systems. Moreover, this research also explores the machine learning/deep learning-based algorithms and their application in the domain of wireless communication. The performance analysis shows that the developed algorithms outperform the existing spectrum sensing techniques in terms of probability of detection, false alarm probability and total error probability.
