1. A digital repeater, comprising:
a plurality of donor antennas;
a plurality of service antennas;
a plurality of signal processing paths each comprising a first transceiver coupled to at least one of the donor antennas, a second transceiver coupled to at least one of the service antennas, and a digital signal processor coupled to the first and second transceivers; and
a controller coupled to the plurality of signal processing paths, the controller adapted to configure the repeater for a multiple-input-multiple-output (MIMO) operating mode and a carrier aggregation (CA) operating mode.
