Stability of the semi-implicit Milstein numerical method for the stochastic differential delay equations
The paper deals with the stability of the semi-implicit Milstein method for stochastic differential e-quations with time delay. By studying the difference equation, which is the outcome of applying the numerical method to a linear test equation, conditions under which the method is MS-stable and GMS-stable are determined. Moreover, some numerical experiments are given.
This paper presents a kind of symbol synchronization based on cyclic prefix.This algorithm based on ML estimation algorithm,improve and simplifies symbol synchronization method in the operation,not only optimises the system in hardware resources, but also improves the performance of estimation.By simulating in Matlab and implementing in FPGA based on the IEEE 802.11a,we successfully further verified the feasibility of the algorithm.The results show that the system is reliable and can meet the design requirements.
