Distributed video coding of Wyner-Ziv frames using Turbo Trellis Coded Modulation

2006 International Conference on Image Processing, 2006
In this paper, we present a novel distributed video coding algorithm based on turbo trellis coded modulation (TTCM). As in the conventional turbo based Slepian-Wolf encoder, quantised information is applied to the TTCM encoder and parity bits are generated from both constituent encoders. However, TTCM symbols are not generated at the encoder since they

Savingmemory in turbo trellis coded modulation using the sliding window

The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004
Turbo trellis coded modulation (TTCM) invented by Patrick Robertson adapted the bandwidth efficiency of TCM and iterative decoding of turbo codes and presented better performance without bandwidth expansion [P. Robertson et al., 1996]. But TTCM has a difficulty of implementing a hardware owing to decoder complexity. So, we need efficient scheduling and

Turbo trellis coded modulation on partially coherent fading channels

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
We design parallel concatenated trellis coded modulation (PC-TCM) schemes at 1 bit/sec/Hz for 8-PSK and 8-QAM over the following discrete two-dimensional (2D) channels: (a) a slow-fading Rayleigh channel with discrete carrier tracking by a phase locked loop (PLL), where the PLL signal-to-noise ratio (SNR) is proportional to the fading amplitude squared;

Turbo-trellis coded modulation under channel estimation inaccuracies

2010 18th Iranian Conference on Electrical Engineering, 2010
Turbo-trellis coded modulation (TTCM) schemes are designed for reliable transmission over quasi-static fading channels. Assuming pilot-assisted channel estimation, practical limitations in power and the number of pilots lead to imperfect channel estimates. A general method for robust receiver design under channel estimation errors was recently proposed

Layered turbo trellis-coded modulation for cooperative communications [PDF]

, 2016
In this thesis, we propose a suite of Turbo Trellis Coded Modulation (TTCM) aided transmission schemes designed for cooperative communications. Our objective is to combine Coded Modulation (CM) schemes with layered modulation arrangements in the context of cooperative communications for the sake of improving both the flexibility and power-efficiency of
