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