First Claim
1. A bidirectional communication system, the system comprising:
- a first remote unit for communicating with a host unit using orthogonal frequency division multiplexing, the host unit communicatively coupled to a plurality of remote units in a multipoint-to-point configuration;
wherein the first remote unit is configured to transmit at least one of a plurality of tones, the at least one of a plurality of tones modulated with upstream information using orthogonal frequency division multiplexing; and
wherein the first remote unit selects an error correction degree for a first tone of the at least one of a plurality of tones based on error correction information received from the host unit, and encodes upstream information transmitted on the first tone based on the error correction degree.
