Class Information
Number: 714/786
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)
Description: Subject matter in which information bits are encoded to generate a plurality of check bits, each check bit is generated as a function of a different plurality of information bits and is interspersed among the information bits at predetermined intervals with no natural beginning point or ending point (i.e., there is no length restriction for the encoded data).
