Abstract
The invention relates to a method and arrangement for advantageously decoding and channel correcting a convolutionally encoded signal received over a transmission path. The signal comprises code words and the arrangement comprises a neural network comprising a set of neurons which comprise a set of inputs and an output. The received code words ( ) and at least some of the output signals ( ) of the neural network neurons are connected to the inputs of the neurons, and the neurons comprise means ( ) for multiplying at least some of the neuron inputs prior to combining means ( ). The arrangement also comprises means ( ) for estimating the transmission channel. Further, estimated channel data ( ) is connected to the inputs of the neurons and a predetermined neuron is arranged to give an estimate of the channel-corrected and decoded symbol in its output signal.
