A new parameters estimation approach for mixed sources is proposed in this paper, which is under the sparse signal reconstruction framework. By reconstructing of covariance matrix, directions of arrival (DOAs) in the far-field part were estimated with an l1-svd-like method directly. Then the subspace difference method was adopted to obtain the near-field covariance matrix, and the relative DOAs can...
This paper proposes a spatial time-division multiple access (STDMA) based scheme (STBS) to enhance the system throughput in cognitive radio wireless networks. Especially, the proposed scheme is suitable for the situation when the available number of channels is far less than the number of secondary users (SUs). The system design includes: 1) a novel criterion based on SINR constraint (SC) to determine...
