Method and apparatus for channel coding and decoding for modulation schemes with memory

Abstract

For transferring digital information in the form of consecutive symbols from a transmitter over a transmission channel susceptible for intersymbol interference to a receiver, the following steps are taken in succession: a) encoding the digital information to be transmitted with an outer code (202), b) interleaving the encoded digital information to be transmitted (203), c) encoding the interleaved encoded digital information with a recursive inner code (204) and in conjunction therewith modulating the encoded interleaved encoded digital information onto a carrier (205), d) transmitting the carrier containing the modulated encoded interleaved encoded digital information, e) receiving the transmitted carrier containing the modulated encoded interleaved encoded digital information, f) producing an estimate of the characteristics of the transmission channel (208), g) converting the received carrier into consecutive symbols in a SISO equalisation process using the produced estimate of the characteristics of the transmission channel (209), h) deinterleaving the consecutive symbols (210), and i) decoding the deinterleaved consecutive symbols in a SISO decoding process (211).
