| Abstract: | In order to meet the requirements of telemetering data real-time processing and net communication, Windows NT operating system is adopted. Communication protocol between the computer and spread spectrum receiver is worked out. Two kinds of data transmission modes PIO and DMA are studied. Device driver program and user detecting program which adapt to 40.26 kbit/s data rate are written. Data communication between the bus structure spread spectrum receiver and computer is realized. |
