Abstract
Transport of differential signals is provided. In one aspect, a telecommunications system includes a first unit and a second unit. The first unit can calculate a differential signal from an original signal. The differential signal can represent a change in signal levels between constant time intervals in the original signal. The second unit can estimate the original signal from the differential signal received from the first unit over a communication medium.

A data compression method for digital radio frequency (RF) transport, the method comprising:
- obtaining a plurality of samples of a first digital data stream at a first component of a digital RF transport system;
- compressing the plurality of samples into a second digital data stream, where at least some of the samples of the second digital data stream is calculated as function of different samples of the first data stream;
- transmitting the second digital data stream over a communication medium to a second component of the digital RF transport system;
- at the second component of the digital RF transport system, estimating at least one statistical characteristic of the first digital data stream based on the second digital data stream;
- generating a third digital data stream at the second component of the digital RF transport system as a function of the at least one statistical characteristic and the second digital data stream;
- converting the third digital data stream into an analog RF signal;
- and
- transmitting the analog RF signal from the second component of the digital RF transport system.

A digital radio frequency (RF) transport system, the system comprising:
- a first component configured to obtain a plurality of samples of a first digital data stream and compress the plurality of samples into a second digital data stream, where at least some of the samples of the second digital data stream is calculated as function of a different samples of the first data stream;
- a second component communicatively coupled to the first component by a communication medium, wherein the first component transmits the second digital data stream over the communication medium to the second component;
- wherein the second component estimates at least one characteristic of the first digital data stream based on the second digital data stream and generates a third digital data stream as a function of the at least one characteristic and the second digital data stream;
- wherein the second component is configured to convert the third digital data stream into an analog RF signal and transmit the analog RF signal from the second component.
