TRANSPORT DATA REDUCTION FOR DAS SYSTEMS
First Claim
1. An endpoint element of a distributed antenna system having multiple endpoints coupled together by serial data links, comprising:
- processing circuitry configured for processing a plurality of digital signals, including first and second digital signals, for conditioning the signals;
compression circuitry configured for compressing at least one of the first and second digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings;
circuitry configured for combining the digital signals into a single digital stream;
circuitry configured for combining and time division multiplexing the single digital stream of the digital signals onto a serial data link with the compression settings;
signal transmission circuitry configured for transmitting the digital signals and compression settings to another endpoint element over the serial data link.

Abstract
An endpoint element of a distributed antenna system includes processing circuitry configured for processing a plurality of digital signals for conditioning the signals and compression circuitry configured for compressing at least one of the digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings. The digital signals are combined into a single digital stream and combined and time division multiplexed onto a serial data link with the compression settings. The digital signals are also transmitted with compression settings to another endpoint element over the serial data link.
