A method and device for processing signal sampling-point data (IQ data). The method comprises: converting time-domain signal sampling-point data, which is to be transmitted, into frequency-domain signal sampling-point data, encoding said frequency-domain signal sampling-point data, and then sending same. The described technical solution uses the frequency-domain features of IQ data in an LTE system to convert, at the sending terminal, time-domain IQ data into frequency-domain IQ data, remove redundant information, and then encode the data. This reduces the number of encoding iterations and achieves more effective compression of CPRI data in an LTE system, thereby satisfying current requirements for transmission bandwidth in transmission access networks, and allowing for the quick and controlled high-efficiency compression and decompression of CPRI data in an LTE wireless base station system. |
