Revisiting Binary Sequence Length Requirements for the Accurate Emulation of Highly Dispersive Transmission Systems
Sequence Length Accurate Emulation Highly Dispersive Transmission Systems
2015/7/31
For accurate emulation, pseudo-random sequence lengths need not exceed requirements of Monte-Carlo theory, scaling like the inverse of the expected bit error rate, even with strong inter-symbol correl...
