Automatic gain control system for a multi-user ofdm digital transmission system using the electric grid

摘要

Automatic gain control for digital OFDM transmission system over the electricity network multiuser. It has a plurality of user equipments and head-end two way communication over the electricity network. Its essential features are: one carrier to carrier treatment on transmission signals and reception signals on control and power transmission equipment. The system makes it possible to reach the maximum number of users achieve maximum transmission capacity, admitting signals from very close and very distant users, prevent floods from occurring, enter the maximum average power over the range available for communication and minimize number of bits necessary for the analog / digital conversion in reception.
