Abstract: Distributed multiple-input-multiple-output(MIMO)arrays obtain a larger virtual aperture by combining subarrays at different locations. However, subarray spacing leads to sparse spatial ...
Abstract: This letter presents a multi-beam digital predistorter (MB-DPD) for phased-array transmitters. MB-DPD uses a convolutional neural network (CNN) to compensate for nonlinear distortions, ...
