All-digital software-defined cognitive heterogeneous network transceiver architecture

A system for controlling a network, comprising:

• a plurality of remote radio heads, wherein each remote radio head of the plurality of remote radio heads is configured to support multiple radio access technologies;
• a circuit configured to provide interface support to the plurality of remote radio heads;
• and
• a controller configured to control the circuit and the plurality of remote radio heads,
• wherein the circuit is connected to each remote radio head of the plurality of remote radio heads via one or more respective fronthaul communication links, and
• wherein said each remote radio head comprises one or more sampling circuits configured to support the multiple radio access technologies, wherein the circuit is reconfigurable to support adaptive signal processing and sampling of the plurality of remote radio heads.
