Power Allocation in Cognitive MISO Wireless Networks

摘要：

In this paper, a spectrum sharing cognitive radio(CR) multiple input and single output (MISO) system is considered, which consists of a secondary user (SU) having multiple transmit antennas and a single receive antenna and a primary user (PU) have a single receive antenna. The channel state information (CSI) on the link between SU and PU is assumed to be perfectly known at the SU transmitter (SU-Tx). Such a system is subject to interference constraint and transmit power constraint. We formulate multi-constraint optimization problem in its equivalent form, and joint beamforming (BF) and power allocation to obtain the maximization capacity.
