POWER CONTROL AND SCHEDULING IN AN OFDM SYSTEM

摘要

A system and method for power control and scheduling of sub-carriers in an OFDM communication system. The receiver dynamic range can be minimized by a power control loop that attempts to maintain received power over a noise flo or in a predetermined range. If the received power relative to a noise floor in allocated sub-carriers exceeds the predetermined range and the total receive d power is at the minimum, the scheduling system allocates an additional sub- carrier to the communication link. Additionally, if the received power relative to the noise floor is less than the predetermined range minimum, an d the total received power is at a maximum, the scheduling system de-allocates a sub-carrier from the communication link. The scheduling system may also adju st an encoding rate to maintain a relatively constant symbol rate in each sub- carrier.
