Concatenated symbolical MTD16Conclusions 1. Binary MTD algorithms are revealed 35 years, and non-binary - 24 years ago. 2. Complexity of soft versions of QMTD is an absolute minimum of calculations known now. 3. They can get QMTD simulation statistics up to bits for ~1 hour with the usual PC! 4. Hard MTD at PLIS is extremely quick decoder 5. Decisions of QMTD usually well converge to decisions of the optimum decoder (OD) 6. QMTD – is the absolute leader among all algorithms by criteria "complexity - efficiency" 7. QMTD is out of to comparison! Their characteristics are fully unique because of decoding simplicity. 8.We suggest many demo programs from our web-site about various best algorithms. Let's work together!
