Abstract

Method and system encodes a signal according to a code rate that includes a ratio of uncoded bits to coded bits. An outer encoder encodes the signal into code words. An interleaver converts the code words into a byte sequence for wireless transmission. An inner encoder executes a convolutional code to generate an encoded signal. The encoded signal is transmitted over a plurality of subcarriers associated with a wide bandwidth channel having a spectral efficiency associated with the code rate. The outer encoder includes a Reed-Solomon encoder having a rate that increases the code rate of uncoded bits to coded bits.

First claim

What is claimed is:

1. A transmitter, comprising:
an outer encoder operable to encode outbound data to generate at least one code word in a first mode of operation and wherein the outer encoder is disabled from encoding the outbound data in a second mode of operation;
an interleaver operable to interleave the at least one code word in the first mode of operation and interleave the outbound data in the second mode of operation;
an inner encoder operable to use a convolutional c…
