Abstract

A method and apparatus for editing a high-convolutional code for transmisison and its reconversion at a receiver using code puncturing n-output bit streams of a convolutional encoder. The device includes parallel switched data rearrangers at the transmitter provided with control switching circuits which evenly distribute bit streams to the transmission channels. At the receiver, a de-puncturer processes all transmission channels in parallel, downstream of which dummy bits are inserted by a multiplexer and a convolutional decoder subsequently decodes the received data.
