摘要：
Receiver (5) for digital signals which comprises a differential decoding circuit deinterleaving and convolution decoding circuit for received digital signals. The differential decoding circuit restores each received symbol to the original phase it had on transmission. This permits the calculation of optimum metrics(M.sub.k.sup.a,M.sub.k.sup.b)which are used by convolution decoding circuit to provide optimum decoding of received symbols.
