1. A base station comprising:
a communication unit configured to connect to a backbone line to which one or more base stations are connected;
M receive antennas, where M is an integer greater than 1; and
a processor configured to execute:
a first process of acquiring, from among a plurality of signals, a first signal arrived from a first terminal, by processing the plurality of signals with a predetermined process, and acquiring first data by demodulating and decoding the first signal, wherein the plurality of signals are simultaneously received from N terminals, where N is an integer greater than 1, and the first terminal is one of the N terminals;
a second process of generating a second signal by encoding and modulating the first data, the second signal being a replica of a signal arrived from the first terminal and included in the received plurality of signals before the plurality of signals are processed by the predetermined process;
a third process of acquiring third signals by excluding the second signal from the received plurality of signals before the plurality of signals are processed by the predetermined process; and
sequentially repeating the first to third processes for the third signals, with one of N−1 terminals obtained by excluding the first terminal from the N terminals as a new first terminal; wherein
the processor is configured to share the first data acquired by the first process with one or more other base stations through the backbone line; and
the processor is configured to execute, in response to a determination that the N is larger than M, the second and third processes for terminals for which the first data has not been acquired by the first process, using data that correspond to the first data and are received from at least one of the one or more other base stations.
