Abstract: A technology is described for automating deployment of a machine learning model. An example method may include receiving, via a graphical user interface, credentials for connecting to a data store containing a plurality of datasets and connecting to the data store using the credentials. A selection of a target metric to predict using the machine learning model can be received, via the graphical user interface, and datasets included in the plurality of datasets that correlate to the target metric can be identified by analyzing the datasets to identify an association between the target metric and data contained within the datasets. The datasets can be input to the machine learning model to train the machine learning model to generate predictions of the target metric, and the machine learning model can be deployed to computing resources in a service provider environment to generate predictions associated with the target metric.

Abstract: Methods and systems for harmonic intermodulation testing are presently disclosed. The test system includes a signal generator configured to generate a test signal having a first frequency. The test system also includes an antenna system configured to transmit a representation of the test signal and receive a harmonic intermodulation signal. The test system also includes a filter configured to remove signals, from a representation of the harmonic intermodulation signal, over a bandwidth that includes the first frequency. The test system also includes an analysis unit configured to measure a power level of a second frequency contained in the representation of the harmonic intermodulation signal. The analysis unit is also configured to determine a passive intermodulation magnitude at any order based on the power level of second frequency.

Abstract: A system for recovering and demodulating a carrier includes a carrier recovery loop and a data detector. The carrier recovery loop receives the carrier as an input and produces a recovered carrier at a frequency approximately equal to that of the carrier. The carrier recovery loop includes a downconverting mixer, a ×5 multiplier, a ×4 multiplier, and a phase locked loop. The downconverting mixer receives the carrier input, and the phase locked loop provides a VCO reference frequency through the ×5 multiplier to the downconverting mixer, which provides a frequency shifted signal. The frequency shifted signal is passed through the ×4 multiplier as input to the phase locked loop. The data detector receives the carrier and the recovered carrier as inputs and uses the recovered carrier to demodulate the carrier and detect I channel data and Q channel data.
