Latest Patents

Frank A Alder holds a patent for an "Apparatus and method of CTCM encoding and decoding for a digital communication system." This patent describes a method for systematically building a multi-dimensional (n, D, L) circular trellis coded modulation (CTCM) encoder. The encoder is designed to optimize energy efficiency, ensure strong tail biting, and achieve maximum minimum distance (d) of trellis paths. The communication system disclosed in the patent includes a CTCM encoder with a permuted state structure, a transmitter, a receiver, and a CTCM decoder. This system is capable of decoding received transmissions without prior knowledge of the starting state of the circular trellis path, thereby recovering the sequence of information bits.
