Class Information
Number: 714/794
Name: Error detection/correction and fault detection/recovery > Pulse or data error handling > Digital data error correction > Forward error correction by tree code (e.g., convolutional) > Maximum likelihood
Description: Subject matter where a decoder selects the sequence out of all the possible transmitted sequences which is most likely to match the received data sequence and determines corresponding digital (data) information.
