Abstract

A distributed base station system is provided by the present invention. The system includes a base-band processing unit, a remote radio frequency unit and a frequency domain processing unit; said base-band processing unit is used for implementing downlink base-band processing for the downlink base-band signal and sending the result of the downlink base-band processing to the frequency domain processing unit; said frequency domain processing unit is used for receiving the result of the downlink base-band processing sent from said base-band processing unit, implementing downlink frequency domain decompression for said result of the downlink base-band processing, sending the result of said downlink frequency domain decompression to said remote radio frequency unit, implementing uplink frequency domain compression for an uplink base-band signal, and sending the result of said uplink frequency domain compression to said base-band processing unit; said remote radio frequency unit is used for receiving the result of the downlink frequency domain decompression sent from said frequency domain processing unit and implementing carrier modulation for the result of said downlink frequency domain decompression.
