An 850-nm VCSEL carried 16-QAM OFDM transmission at 56 Gbit/s is demonstrated by using the pre-leveling technology, which reveals an optimized signal-to-noise ratio, error vector magnitude and bit-error-rate of 16.4 dB, 15.1% and 1.2×10−3, respectively.
This paper investigates the problem of mean-square asymptotic stability of uncertain neural networks with time-varying delay and stochastic noise. Based on generalized Finsler lemma and the linear matrix inequality (LMI) optimization technique, an improved delay-dependent stability criterion is developed. It is shown that the new stability criterion is less conservative and less computationally complex...
In the view of the situation that the impact on the power analysis attacks is little studied,the impact of the clock frequency is discussed and analysed in this paper. The power trace is the object that is studied by the power analysis attacks. The clock frequency has impact on the data dependency characteristics and the operation dependency characteristics of the power trace by influencing the number...
We propose a new two-dimensional (2D) modulation code for holographic data storage (HDS) systems. This code has a code rate of 3/4 and is called 6:8 variable-weight (VW) modulation code. Simulation results show that the 6:8 VW modulation code achieves a bit-error-rate (BER) of 10-3 with a coding gain of 5 dB and it outperforms the conventional balanced codes. In addition, we propose a modified decoding...
