Joint Multilevel Turbo Equalization and Continuous Phase Frequency Shift Keying

EURASIP Journal on Wireless Communications and Networking, 2008
A novel type of turbo coded modulation scheme, called multilevel turbo coded-continuous phase frequency shift keying (MLTC-CPFSK), is designed to improve the overall bit error rate (BER) and bandwidth efficiency. Then, this scheme is combined with a new

Performance Evaluation of Parallel Concatenated Chaos Coded Modulations

Journal of Communications Software and Systems, 2008
In this article we study the performance of a class of parallel concatenated encoders similar to a turbo trellis coded modulation, but where the constituent encoders are chaos coded modulators.

Concatenated space-time block coding with asymmetric MPSK TCM

Tongxin xuebao, 2010
The field of concatenated space-time block coding （inner） with trellis coded modulation （outer） has recently attracted interest as a means of jointly considering the error correction coding gain and diversity gain possible without bandwidth expansion and
