#$%^&*AU2020200070A120200130.pdf#####ABSTRACT A system and methods are described which compensate for the adverse effect of Doppler on the performance of DIDO systems. One embodiment of such a system employs a distributed antenna system comprising: a plurality of subsets of the distributed antennas selected to wirelessly communicate to a plurality of subsets of users based on the Doppler spread of users relative to the distributed antennas. 7755/62 LUO Z n * n' Len LnA cn~ I LA I I~ In 0 ( LnLn cu LA 0 to
