Abstract
Methods and systems for processing a noisy time series input to detect a signal, generate a de-noising mask, and/or output a de-noised time series output are provided. The input is transformed into one or more datagrams, such as real and imaginary time-frequency grams. The datagrams are stacked and provided as first and second channel inputs to a neural network. A neural network is trained to detect signals within the input. Alternatively or in addition, the network is trained to generate a de-noise mask, and/or to output a de-noised time series output. Implementation of the method and systems can include the use of multiple deep neural networks (DNNs), such as convolutional neural networks (CNN's), that are provided with inputs in the form of RF spectrograms. Embodiments of the present disclosure can be applied to various RF devices, such as communication devices, including but not limited to multiple inputs multiple output (MIMO) devices and 5G communication system devices, and RADAR devices.
