Background Signal Control Platform And A Gps Receiver

The research on the Background Signal Simulator is based on the idea of the Soft Wireless. On May 1992,Joe Mitola,the prestigious scientist of Co. MTTRE,advanced the definition of the Soft Wireless for the first time in the American Telecom Annual Meeting. His idea is based on the fact that the pivot of the Soft Wireless structure is to put the Broad Band A/D and D/A conversion near to antenna by all means,and to define the functions of the transmitter-receiver as many as possible in the forms of software(namely realized by software).The technology of Background Signal Simulator puts the focus on the methods used to realize the software,namely to exploit the functions of the hardware (for example,DSP FPGA or ASIC) through the idea of software design,and to produce(realize) wireless signals by high speed LSI and software programming.This paper introduces some practicable ways to realize the design of Background Signal Simulator console software,database exploitation and the data processing for the GPS receiver(GN-79). To meet the needs of these superiorities such as simple maneuverability,modularization and high secrete security,we considerably think of those requirements in the aspects of the signal-producing,hardware-setting,timing and orientation,user setting and so on,during the period when we design the software,make the database accessing down to the bottom layer,and obligate full space for its improvements of software modification and function expansion.GPS receiver offers the information of timing and orientation for the system,which makes it greatly effective to the system. In this paper,we introduce in detail the use of GPS receiver and its data processing,in addition to a large number of formula deductions. These formulas can all be used in programming directly.
