Abstract
A signal transmitter and a signal receiver for interpreting a received message are provided. The receiver is configured to perform the steps of: decoding a first part of the message using a channel decoding scheme with a predefined set of decoding parameters to form a first data block; and subsequently decoding a second part of the message using the channel decoding scheme with decoding parameters that are at least partially dependent on the content of the first data block.
Claims20
An apparatus for interpreting received data related to a message, the apparatus comprising:
- a demultiplexer configured to demultiplex the received data into a first portion and a second portion, wherein the first portion includes at least control data;
- and
- a decoder configured to:
- decode a first part of the message, based on the first portion of the received data, using a channel decoding scheme with a predefined decoding parameter to form a first data block,
- recover a decoding parameter for the second portion of the received data from the first data block, and
- decode a second part of the message, based on the second portion of the received data, using the channel decoding scheme with a decoding parameter that at least partially includes the decoding parameter recovered from the first data block.
An encoder for encoding a data signal, the encoder comprising:
- a channel encoder configured to store a predefined encoding parameter;
- and
- a multiplexer configured to combine the data signal and a further encoding parameter into a message, wherein a first part of the message comprises the further encoding parameter,
- wherein the channel encoder is further configured to map the message onto a codeword,
- wherein a first portion of the codeword allows the first part of the message to be decoded independently of a second part of the message, and
- wherein a second portion of the codeword allows the second part of the message to be decoded based on the further encoding parameter comprised in the first part of the message.
A method for interpreting received data related to a message, applied to a signal receiver, the method comprising:
- demultiplexing, by a demultiplexer, the received data into a first portion and a second portion, wherein the first portion includes at least control data;
- decoding, by a decoder, a first part of the message, based on the first portion of the received data, using a channel decoding scheme with a predefined decoding parameter to form a first data block;
- recovering, by the decoder, a decoding parameter for the second portion of the received data from the first data block;
- and
- decoding, by the decoder, a second part of the message, based on the second portion of the received data, using the channel decoding scheme with a decoding parameter that at least partially includes the decoding parameter recovered from the first data block.
A method for encoding a data signal, the method comprising:
- storing, by an encoder, a predefined encoding parameter;
- combining, by the encoder, the data signal and a further encoding parameter into a message, wherein a first part of the message comprises the further encoding parameter;
- and
- mapping, by the encoder, the message onto a codeword,
- wherein a first portion of the codeword allows the first part of the message to be decoded independently of a second part of the message, and
- wherein a second portion of the codeword allows the second part of the message to be decoded based on the further encoding parameter comprised in the first part of the message.
