Abstract
The spectrum sensing acquired importance due to ever-growing demands for the high data rates. It is one of the prominent functions in the cognitive radio, 4G, and beyond 4G cellular systems. Different facets of spectrum sensing methods are examined from a cognitive radio and multi-input and multi-output (MIMO) systems perspective. The major task of cognitive radio is to identify the unused spectrum and thereby allocating that spectrum to the required users without causing interference to the other users, and the important task of 4G system is to provide user demanding bandwidth by detecting the existence of the user in order to allocate the unused subcarrier channels to the required users. Hence, spectrum sensing is the key feature of cognitive radio. In this paper, a new energy detection-based spectrum sensing for MIMO wireless channel is proposed. The proposed technique performs better in case of higher order antenna configurations compared to lower order.
