The present disclosure is directed to a transmitter 200 that includes a first block encoder 450 operable to block encode at least a first portion of a multi-band orthogonal frequency division modulation signal. The transmitter 200 also includes a convolution encoder 304 operable to convolution encode the output of the first block encoder 450. A method of communicating is also disclosed. The method comprises block encoding a first portion of a message to produce a first outer code word. The method includes convolution encoding the first outer code word to produce a first inner code word. The method also includes transmitting the first inner code word as part of a multi-band orthogonal frequency division modulation signal.
