Remote end module, near end module, system and method for radio remote head

The invention provides a radio remote system, which comprises a remote end module for converting between an analog radio-frequency signal and a baseband signal and processing the redundancy in the baseband signal, and a near end module for performing baseband processing on the baseband signal of which the redundancy is processed in the remote end module. The invention also provides the remote end module and the near end module in the radio remote system and a radio remote method. The radio remote system, the radio remote method, and the remote end module and the near end module in the radio remote system can reduce data transmitted between the remote end module and the near end module, reduce the wire transmission quantity between the remote end module and the near end module, and further reduce the cost and the design difficulty of radio remote technology.
