Abstract
A distributed antenna system (DAS) according to an aspect of the inventive concept includes a first node unit for receiving first digital data in accordance with a digital interface standard from a base station, converting the first digital data into second digital data in accordance with a DAS frame standard, and a second node unit for receiving the second digital data from the first node unit, and restoring the first digital data based on the second digital data.
Claims13
A distributed antenna system (DAS), comprising:
- a first node unit comprising at least one first processor configured to receive first digital data in accordance with a digital interface standard from a base station, convert the first digital data into second digital data by resampling the first digital data or a portion of the first digital data at a frame rate in accordance with a DAS frame standard that applies to the DAS and by performing a framing process on the first digital data or the portion of the first digital data resampled in accordance with the DAS frame standard;
- and
- a second node unit comprising at least one second processor configured to receive the second digital data which is framed in the DAS frame standard from the first node unit, and restore the first digital data based on the second digital data,
- wherein the at least one first processor of the first node unit is further configured to convert overhead data included in the first digital data in accordance with the digital interface standard into overhead data in accordance with the DAS frame standard.

A communication device, comprising:
- at least one memory;
- and
- at least one processor to implement:
- a resampler configured to receive first digital data in accordance with a digital interface standard from a base station, and resampling the first digital data or a portion of the first digital data at a frame rate in accordance with a distributed antenna system (DAS) frame standard that applies to the DAS;
- a framer configured to generate second digital data by performing a framing process on the first digital data or the portion of the first digital data resampled in accordance with the DAS frame standard;
- and
- an overhead processor configured to convert overhead data included in the first digital data in accordance with the digital interface standard into overhead data in accordance with the DAS frame standard.
