Abstract:
1. A method of transmitting first data and receiving second data in a cable modem system comprising the steps of: encoding the first data using a forward error correction (FEC) scheme to generate FEC encoded data; encoding the FEC encoded data using a Turbo encoding scheme to generate Turbo encoded data; mapping the Turbo encoded data to a modulation scheme to generate mapped data; transmitting the mapped data over a cable channel; demodulating the second data received over the cable channel to generate demodulated data; decoding the demodulated data using a Turbo decoding scheme to generate Turbo decoded data, wherein symbol estimates for the Turbo decoded data are generated using between 8 and 16 iterations; and decoding the turbo decoded data using the FEC decoding scheme.
