Abstract:
Decode and forward buffer aided relay selection and transmission power allocation systems and method are provided for cognitive radio network that is equipped with multiple-input-multiple-output (MIMO). A low complexity MIMO-based relay selection scheme that maximizes the single-hop normalized sum rate of the primary network (PN) and secondary network (SN) is proposed including a sub-optimal antenna transmission power allocation scheme that maximizes the single-hop normalized sum rate of the PN and the SN is proposed. For power optimization, first, optimal expressions for the transmission power per antenna of both the PN and SN nodes are derived separately. The derived expressions are then used in an iterative algorithm to produce a near-optimum solution that maximizes the normalized sum rate per time slot.

Claim (Index 14):
A method for relay selection within a cognitive radio network, the method being performed by a processor, the method comprising:\n identifying one or more primary source devices and primary destination devices within a primary network of the cognitive radio network; identifying one or more secondary source devices and secondary destination devices, and a predetermined number of cognitive relays within a secondary network of the cognitive radio network; transmitting data packets from the primary network for every time slot during network operation on a continuous basis; and selecting a source relay link or a relay destination link within the secondary network to transmit predetermined data based on a modified Max-Link relay selection with set criterion of R i Opt = max i \ue89e ( R S p , R p ( 1 ) + R S , R i , R S p , R p ( 2 ) + R R i , D ) . where R S p, (1) R p  and R S p, (2) R p  are the normalized rates of the primary network, R s,Ri  is the channel matrix for a link between source and relay i, and R Ri,D  is the channel matrix for a link between relay R i  and destination D, wherein the one or more primary source devices, primary destination devices, secondary source devices, secondary destination devices and cognitive relays are multiple-input multiple-output (MIMO) devices, the method further comprising identifying a MIMO channel for transmission on a source-relay link, or a relay-destination link on the secondary network: dividing the MIMO channel into a predetermined number of parallel, independent, and ranked channels; and enhancing efficiency of power usage by\n allocating a transmission power budget, and \n distributing the transmission power budget among primary and secondary transmitting antenna devices at a predetermined time interval.
