内容简介：Multi-antenna technologies have been adopted in several standards, such as IEEE 802.11n, WiMAX and3GLTE, to achieve more reliable and high rate wireless transmissions. When these systems share a radio spectrum with other primary systems and operate in a secondary basis, a nature question to be asked is how these multiple antennas can be used to assist for the cognitive radio design. In this talk, both opportunistic spectrum access (OSA) model and concurrent spectrum access (CSA) model will be considered. For OSA model, I will review the design challenges for spectrum sensing, and present the sensing techniques using multiple antennas. For CSA model, cognitive beamforming design will be discussed, including transit optimization, and learning-training-transmission tradeoff.
