Beamforming in Cognitive Radio Systems

This MATLAB code implements beamforming techniques for cognitive radio applications. The implementation dynamically adjusts antenna transmission parameters including power levels and radiation patterns according to the spatial distribution of nodes within network topologies. The algorithm employs spatial signal processing to optimize directional transmission, potentially incorporating techniques like MVDR (Minimum Variance Distortionless Response) or LCMV (Linearly Constrained Minimum Variance) beamformers to enhance spectral efficiency while minimizing interference. Originally developed as part of a doctoral dissertation, this code provides a foundation for implementing adaptive beamforming in cognitive radio environments. The implementation likely includes functions for channel estimation, direction-of-arrival calculation, and weight vector computation for antenna arrays. Should you have any technical questions regarding the implementation details or algorithm applications, please feel free to inquire for further clarification.
