Spatial Characteristics of Distortion Radiated From Antenna Arrays With Transceiver Nonlinearities

The distortion from massive multiple-input multiple-output base stations with nonlinear amplifiers is studied and its radiation pattern is derived. The distortion is analyzed both in-band and out-of-band. By using an orthogonal Hermite representation of the amplified signal, the spatial cross-correl...
