Abstract
A system and method for coding and decoding an information signal sent through a communication system. The system includes: an encoder for encoding the information signal without adding additional information and for sending an encoded information signal; and a soft bit decoder including a-priori information related to the communication system for receiving the encoded information signal and decoding the encoded information signal using the a-priori information.
Claims18
A method for coding and decoding an information signal sent through a communication system comprising:
- preparing a-priori information related to the communication system;
- receiving an information signal;
- encoding the information signal at an encoder without adding additional information;
- sending the encoded information signal through a channel of the communication system;
- receiving the encoded information signal at a decoder;
- and
- decoding the encoded information signal using the a-priori information.
