DIGITAL BASEBAND TRANSPORT IN TELECOMMUNICATIONS DISTRIBUTION SYSTEMS

摘要

A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

1. A distributed antenna system, comprising:
a head end unit configured to communicate channelized digital baseband signals with remotely located units, the channelized digital baseband signals including call information for wireless communication, the head end unit including circuitry configured to:
receive downlink signals from at least one base station;process the downlink signals into downlink channelized digital baseband signals;format the downlink channelized digital baseband signals for transport together;packetize and packet schedule the downlink channelized digital baseband signals into downlink packetized baseband signals; andtransmit the downlink packetized baseband signals to the remotely located units.
