摘要:
A multiple-input multiple-output (MIMO) communication system includes a base station and a relay station that are connected through an optical fiber. The relay station wirelessly transmits through a plurality of antennas a signal received from the base station. The base station includes a plurality of symbol mappers for mapping input bit streams into a plurality of symbol signals; a MIMO multiplexer generating a plurality of exchange signals by exchanging bits of the symbol signals; and a plurality of code spreaders generating a plurality of spread signals by band spreading the exchange signals. The adoption of a wire transmission scheme for connecting the base station with the relay station through a single optical fiber provides benefits in cost reduction and complexity as the number of electrical-to-optical converters is reduced, and the bandwidth is superior to those in wireless transmission scheme
