The performance of trellis-coded modulation

TENCON'92 - Technology Enabling Tomorrow, 2003
Trellis-coded modulation (TCM) in an 8-PSK (phase shift keying) scheme is more power efficient than uncoded QPSK at the same spectral efficiency on perfect coherent detection. For the same signal-to-noise ratio (SNR) of phase reference, the sensitivity to phase offset for 8-PSK is more serious than for uncoded QPSK.

Trellis-coded M-ary orthogonal modulation

Proceedings IEEE Symposium on Computers and Communications, 2002
We have introduced the trellis-coded M-ary (M=32) 4-dimensional (4-D) orthogonal modulation scheme. Here, a rate 4/5 convolutional encoder generates one of 32 possible symbols every T seconds. Then the signal mapping for 32 symbols is performed by a M-ary 4-D orthogonal modulator.

Power Allocation in Concatenated Trellis Coded Modulation

IEEE Transactions on Wireless Communications, 2008
In this paper, power loading algorithms are presented for limited diversity fading channels with channel state information at the transmitter. Limited diversity channels are those that offer moderate levels of diversity (about 3-5) such as those encountered in orthogonal frequency division multiplexing (OFDM) based indoor wireless networks.

A comparison of trellis modules for binary convolutional codes

IEEE Transactions on Communications, 1998
Summary: A convolutional code can be represented by the conventional trellis module or the ``minimal'' trellis module based on the BCJR trellis for block codes. For many convolution codes the trellis complexity (TC) of the minimal module is significantly less than the TC of the conventional module.
