Super resolution and deconvolution of angular power spectra

Linear antenna arrays have an inherent angular variance, which makes them difficult to use for angular channel characterisation. Through operation in the virtual Doppler domain at the base station (BS)-an invariant convolution between environment Doppler response and antenna array factor can be exploited. This enables the use of a deconvolution procedure, providing increased resolution in the Doppler and angular spectrum. The Doppler domain description also results in a subtraction property for the Doppler spread. Thus providing a super resolved statistical dispersion measure for channel characterisation. Furthermore the statistics of the received amplitude and phase response along the array are given
