Pragmatic TCM Decoder and Its Method Using Coset Mapping

摘要

1. the art that the invention defined in the claims; The present invention relates to a program will lag meotik (Pragmatic) TCM (Trellis Code Modulation) a computer-readable recording medium recording a program for realizing the method and decoder, and a method using a koset mapping.; 2. The invention attempts to solve the technical challenges; The present invention using a koset mapping sector phase quantizer: a computer-readable recording a program for realizing the above method and to a soft decision pragma meotik TCM decoder and method that, without going through a (SPQ Sector Phase Quantizer) that aims to provide a recording medium.; 3. Resolution of the subject matter of the invention,; The invention, koset mapping (coset mapping) for using pragma meotik (pragmatic) TCM (Trellis Code Modulation) is determined in the decoder, the received demodulated signal (the "received demodulated signal" hereinafter) constellation on I (In the -phase) axis and the Q (Quadrature-phase), using the coordinate axis after obtaining a phase of the received demodulated signal, the obtained phase and the constellation for decoding data coded using the I-axis and Q-axis coordinates on the koset mapping means for obtaining information (coset mapper); Decoding means for decoding the encoded data using the information derived in the koset mapping means; Constellation I (In-phase) axis on the received demodulated signal and the Q (Quadrature-phase) comprises a non-coding code decoding means for obtaining a non-encoded data by using the data decoded by the coordinates, and the decoding means axis do.; 4. An important use of the invention,; The invention yiyongdoem like pragma meotik TCM decoder.
