摘要：The invention relates to a method and an arrangement for decoding aconvolutionally encoded signal which comprises code words and which arrangementcomprises a neural network which comprises a set of neurons comprising a set of inputs

and an output, and the received code words (800) are applied to the inputs of theneurons, and which arrangement comprises means (806) for combining some of theinputs of the neuron in the neuron. In order to enable efficient decoding of the

convolutional encoding, some of the output signals (802) of the neural network neuronsare fed back to the inputs of the neuron and the neuron comprises means (804) formultiplying at least some of the inputs of the neuron with one another before thecombining means (806) and that the output signal of a predetermined neuron comprisesan estimate of a decoded symbol.
