Abstract: One embodiment described herein relates to a method of predicting the performance of a communication system on a transmission channel. The system may comprise a transmitter suitable for applying bit interleaved coded modulation to information bits issued by a source to generate coded symbols, these coded symbols being transmitted by the transmitter over the transmission channel. The coded modulation may be based on a turbo-code comprising at least two constituent codes. The system may also comprise an iterative receiver, suitable for performing an iterative interference cancellation technique to process the coded symbols received from the transmission channel, the iterative receiver comprising an equalizer, a demodulator, and a turbo-decoder that are activated during each iteration performed by the iterative receiver. The turbo-decoder may comprise at least two decoders suitable for decoding the respective constituent codes of the turbo-code, the decoders being suitable for interchanging probabilistic quantities in an iterative manner.
