Spe- cifically,the realization schemes of different multi-connection modes are analyzed and compared in terms of the data flow,scheduler,HARQ process and frequency handover techniques.

Specifically, the realization schemes of different multi-connection modes are analyzed and compared in terms of the data flow, scheduler, HARQ process and frequency handover techniques.

An improved band-switching circuit is adopted to save band-switching time.

Study Switching for Frequency of Pilot Beacon on CDMA Network Optimization

Adjusting the switching frequency at which the signal is time-division transferred, the basic frequency signal is transferred through n branches within one signal cycle efficiently, and each branch works for a fixed 1/n of the signal period.

In this paper,first of all,we study the stabilization of the switched linear systems composed of stable subsystems by means of the switching frequency.

According to the analysis of computer audio and video signals, the circuits of center control module, VGA switch module, audio switch module and volume regulate module have been given in detail, meanwhile the work principle is also expatiated.

In this paper,we introduced the video and audio switch system of multimedia central controller which based on ARM,present the principle、design project、software model and hardware model of multimedia video and audio switch.
