PCT No. PCT/IB95/01134 Sec. 371 Date Aug. 23, 1996 Sec. 102(e) Date Aug. 23, 1996 PCT Filed Dec. 15, 1995 PCT Pub. No. WO96/20546 PCT Pub. Date Jul. 4, 1996A digital transmission system, such as a mobile radio system, having a transmitter for transmitting codewords which are derived from a digital signal, and a receiver for receiving codewords, the receiver including a decoder with a prediction filter which is excited by an input signal to produce an estimated digital signal. To improve reconstruction of the digital signal in the event of disturbances, the decoder includes a first switching circuit for switching off the input signal of the prediction filter when a disturbed codeword is received, and a second switching circuit for switching substitute values formed from previous values of the estimated digital signal instead of the estimated digital signal when the input signal is switched off. |
