    Abstract: PROBLEM TO BE SOLVED: To provide a single base station, that supports non-diversity transmission of a 1st-type digital signal and diversity transmission of a 2nd-type digital signal. SOLUTION: The base station 8 includes a primary channel board 12, that modulates and codes a digital signal of the 1st type and a secondary channel board 14, that modulates and codes a digital signal of the 2nd type. A 1st group transmission wireless module 18 receives the digital signal of the 1st type and the digital signal of the 2nd type, and provides a synthesized electromagnetic output signal. Each transmission wireless module is related to each different sector. The transmission wireless module 18 of the 2nd group receives the digital signal of the 2nd type from the secondary channel board 14 and provides a different electromagnetic output signal, to supplement the composited electromagnetic output signal.

    Abstract: A single base station supports the non-diversity transmission of a first digital signal type and the diversity transmission of a second digital signal type. The base station includes primary channel boards for modulating and encoding a first digital signal type and secondary channel boards for modulating and encoding a second digital signal type. A first group of transmit radio modules accept the first digital signal type and the second digital signal type and provides a composite electromagnetic output signal. Each transmit radio module is associated with a different sector. A second group of transmit radio modules accept the second digital signal type from secondary channel boards and provide a diverse electromagnetic output signal for complementing the composite electromagnetic output signal.
