METHOD AND SYSTEM FOR IMPROVING UPLINK PERFORMANCE
First Claim
1. A distributed antenna system comprisingat least one signal regeneration component, the signal regeneration component including a demodulation block adapted to demodulate an input signal and extract information carried by the input signal;
- andre-modulation block adapted to receive the extracted information and to re-generate a signal for transmission through the distributed antenna system.

Abstract
The present invention is directed to improvements for distributed antenna systems and more particularly to methods and systems for improving uplink communications. In one embodiment, Aggregation Point Noise Blocking provides for blocking or filtering the noise contributed by one or more of the branches coupled to an aggregation point that are not carrying the signal from a particular terminal. Signal activity from a given terminal on a particular branch can be identified and that information can be used to selectively block or filter the signal noise contributed by the other branches to an aggregation point. The selective blocking or filtering can also include an attenuation function to attenuate the signal and provide dynamic range smoothing. In another embodiment the signal can be regenerated to produce a signal that has a restored or very high SNR. An uplink regeneration block can be provided which demodulates the uplink signal to recover the transmitted information and then re-modulates the transmitted information to regenerate a signal at a restored or very high SNR.
