SYSTEM AND METHOD FOR EFFICIENT FRONTHAUL COMMUNICATION FOR WIRELESS COMMUNICATION

摘要

A system and method of reducing data-rate requirements of fronthauls for wireless communication is disclosed. In one aspect, the system includes a baseband processing unit and a remote radio head remotely located from the baseband processing unit. The remote radio head is configured to transmit and receive communication signals with the baseband processing unit. The system can also include a fronthaul configured to provide a communication channel between the baseband processing unit and the remote radio head for the communication signals, and a matched filter configured to filter out redundant information from the communications signals before the communications signals are provided to the fronthaul.

1. An apparatus comprising:
a remote radio head (RRH) configured to receive a first plurality of multiple-access wireless signals from a plurality of users and to generate a first baseband signal comprising first symbols from the plurality of multiple-access wireless signals; a matched filter configured to reduce redundancy in the first symbols of the first digital baseband signal to generate a second digital baseband signal comprising second symbols, wherein the second symbols include information from the plurality of users, wherein the second digital baseband signal has reduced bandwidth relative to the first digital baseband signal; and a fronthaul driver configured to communicate the second digital baseband signal through a fronthaul.
