A concatenated encoder capable of coding multiple data bits in parallel and including a first (outer) encoder, a memory, and a second (inner) encoder coupled in cascade. The first encoder receives and codes M data bits in parallel in accordance with a first coding scheme to generate MR code bits. The memory receives and stores unpunctured ones of the MR code bits from the first encoder. The second encoder receives and codes N code bits in parallel in accordance with a second coding scheme to generate coded data. M and N can be any values (e.g., M>=8, N>=4). Each encoder can be a (e.g., a rate ½) convolutional encoder that implements a particular polynomial generator, and can be implemented with one or more look-up tables, a state machine, or some other design.
