Development and demonstration of a software-defined radio array for adaptive beamforming
This paper presents an implementation of a software-defined radio array, which is a low-cost digital beamformer that is suitable for researching and prototyping novel digital beamforming and array processing algorithms. The beamformer is a four-element 2.45 GHz antenna array with antennas driven by a collection of synchronized software-defined radios, which are low-cost transceivers that allow radio functions to be implemented in software using digital signal processing. The array is used for experimental studies on interference cancellation in high-multipath indoor environments. The studies ...
