The present disclosure relates to a distributed antenna system and a signal transmission method. A first remote cascaded chain corresponding to a first channel set and a second remote cascaded chain corresponding to a second channel set are obtained by means of division, such that when a distributed antenna system needs to support multi-channel MIMO, remote units in the first remote cascaded chain and remote units in the second remote cascaded chain only need to be configured with communication link modules, the number of which is less than the number of channels, and the multi-channel MIMO is jointly supported by using the remote units in the first remote cascaded chain and the remote units in the second remote cascaded chain, such that the multi-channel MIMO capability of an overlapping region can be realized.

Distributed antenna system and signal transmission method

Disclosed are a wireless communication system and method and an expansion unit of a flat network architecture. The wireless communication system comprises at least one baseband signal source, an expansion unit (EU) and at least one remote radio unit (RU) connected to the EU. By overlapping the baseband signals output by each baseband signal source, remote transmission and wireless coverage of multimode digital signals are achieved, thereby solving the problem of system performance degradation caused by the interaction of radio-frequency analog signal transmission and optical transmission in the prior art.
