Title:
メッセージのリマッピングおよび符号化
Document Type and Number:
Japanese Patent JP5341158
Kind Code:
B2
Abstract:
Techniques for remapping messages prior to encoding to improve performance are described. L designated messages among K total messages are remapped to L remapped messages, which are associated with L codewords having larger relative distance between these codewords, where L may be much less than K. The L designated messages may be more frequently used messages and/or more important messages. The remapping allows the L codewords with larger relative distance to be sent for the L designated messages, which may improve performance. A transmitter remaps an input message to a remapped message, encodes the remapped message to obtain a codeword, and sends the codeword to convey the input message. A receiver decodes a received codeword to obtain a decoded message and demaps the decoded message to obtain a demapped message, which is an estimate of the input message sent by the transmitter.
