In streaming computing applications, some data can be filtered to reduce computation and communication. Due to filtering, however, some necessary information might be lost. To recover lost information, we use control messages, which carry control information rather than input data. The order between control messages and input data must be precise to guarantee correct computations. In this paper, we...
According to the principle of phase space reconstructing by the scale and its differential of a continuous time chaotic system, the synchronization of Lorenz system is investigated by employing chaos observer synchronization method. A theorem about chaos observer synchronization of Lorenz chaotic system is put forward based on the stability rule. Appling this method into secure communication, a new...
Orthogonal frequency division multiplexing (OFDM) systems require the knowledge of signal-to-noise ratio (SNR) at the receiver in order to optimize the system performance. In general, the noise variance is required by the SNR estimator and the knowledge of noise variance also improves the performance of carrier frequency offset (CFO) and channel state estimations. This paper commences by investigating...
