A decision-feedback multiple symbol differential detection of differentially modulated 16-order (N,M)APSK signal, that is N-PSK on the inner ring and M-PSK on the outer ring (N+M=16), is presented, as well as the optimization of constellation according to the minimum SER (symbol-error-rate). Here we have studied the detection performance, and derived the theoretical expression of SER. It can been...
This paper investigate consensus problems in an extended scale-free network model. It is found that as the network becomes more homogeneous, the convergence speed decreased; however, the maximal tolerate delay time of the network achieving consensus is increased. Therefore, there is a trade-off between the speed of achieving consensus and the robust to the delay time.
In this paper, the simulation models of hydraulic turbine regulating system were developed in a MATLAB/Simulink-based software environment. These nonlinear characteristics of hydraulic turbine and the no-elastic water hammer effect of pressure water supply conduit were considered in the modeling. Some simulation tests have been performed, such as step speed disturbance test on no-load operation and...
