METHOD FOR VARIABLE FORWARD ERROR CORRECTION IN A MULTI-POINT TO POINT ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM
First Claim
1. A method for an orthogonal frequency division multiplexing multipoint-to-point communications system, the method comprising:
- establishing communication between a first remote unit of a plurality of remote units and a host unit, the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point configuration;
transmitting up to a plurality of tones from the first remote unit, the up to a plurality of tones modulated with upstream information using orthogonal frequency division multiplexing; and
encoding the upstream information based on a degree of error correction selected by the host unit.
