Low Complexity Decoding for Punctured Trellis-Coded Modulation Over Intersymbol Interference Channels

, 2013
Classical trellis-coded modulation (TCM) as introduced by Ungerboeck in 1976/1983 uses a signal constellation of twice the cardinality compared to an uncoded transmission with one bit of redundancy per PAM symbol, i.e., application of codes with rates ...

Method of blind reconstruction for trellis‐coded modulation codes

IET Communications, 2014
Since trellis‐coded modulation (TCM) was introduced, it was quickly adopted in modem standards. Unlike blind reconstruction for normal channel coding, blind reconstruction for TCM codes not only requires identifying the correct generator matrix, but also the correct type of constellation mapping. So far this has seldom been reported.

Multiple Trellis Coded Modulation (MTCM): An MSAT-X report [PDF]

Conventional trellis coding outputs one channel symbol per trellis branch. The notion of multiple trellis coding is introduced wherein more than one channel symbol per trellis branch is transmitted.

Trellis coded modulation based distributed channel coding

IET Communications, 2009
A novel technique is described for distributed channel coding in wireless communication networks. The protocol is based on a block fading model of the multi-user uplink channel and on adapting multidimensional trellis coded modulation techniques to a coding theorem derived for the block fading channel.

Performance of OFDM: FSO Communication System with Hybrid Channel Codes during Weak Turbulence

Journal of Computer Networks and Communications, 2019
The performance of orthogonal frequency division multiplexing- (OFDM-) based free-space optics (FSO) depends on various parameters such as number of subcarriers, base band modulation, nature of laser beam, turbulence modelling, and much more.

Trellis-coded MPSK modulation techniques for MSAT-X(sup)1 [PDF]

Various trellis-coded modulated phase shift keying (MPSK) modulation techniques for transmitting 4.8 kbps over a 5 kHz RF channel are considered. The tradeoffs between coherent versus differentially coherent types of demodulation, and interleaving are ...
