A METHOD AND SYSTEM FOR CONVERTING THE DATA SAMPLE RATE IN THE BASEBAND SIGNAL TRANSMISSION

摘要

A method and transmission system for converting the data sample rate in the baseband signal transmission, the method comprises the steps: (a) receiving the data from the antenna by the RF remote unit, and achieving the reduced-sample processing for the data in the baseband by the data sample rate conversion module; (b) Transmitting the data processed via the data transmission channel; (c) processing the data by the data sample rate recovery module before the data is transmitted to the baseband chip, recovering the sample rate to that required by the baseband chip, and running the subsequent process. The method for converting the sample rate of the baseband signal can significantly add the number of RRU connections without affecting the performance.
