Abstract
According to an aspect of the inventive concept, there is provided a signal processing method performed in a distributed antenna system, includes extracting at least a part of sample data corresponding to an occupied frequency band from a digitized analog RF signal; and combining the extracted sample data.
Claims11
A signal processing method performed in a node unit of a distributed antenna system, comprising:
- extracting at least a part of sample data corresponding to an occupied frequency band from a digitized downlink radio frequency (RF) signal;
- converting a frequency of at least a part of the extracted sample data;
- combining the frequency-converted sample data, digitally;
- resampling the digitally combined sample data;
- dynamically allocating the resampled sample data to a transmission frame having an unfixed structure such that a length of the transmission frame is changed based on the resampled sample data;
- and
- converting the resampled sample data allocated to the transmission frame into a signal corresponding to a transport medium.
