Software Radio Instruction Station Research And Design

In recent years, with the rapid development and the drop of price on high speedAnalog-Digital Converts, Digital Signal Processors, high performance ComplexProgrammable Logic Devices, wireless communication is facing a revolution fromhardware to software. So Software Radio technology emerges as the times require. This paper is a research on Software Radio Instruction station technology. Firstly itintroduces the concept of Software Radio, and then put forward the system functionmodel and interrelated key technology of Software Radio. In this paper we have acomplete research about architecture of Software Radio. Secondly we apply SoftwareRadio technology into Instruction Communication field and advance 'SoftwareInstruction Radio', which is a new idea in Instruction Communication receivingequipment. An integrated design scheme was given in this paper in order to realizeInstruction Radio digitized, software, intellectualized. We construct hardware platformbased on MCU/DSP and execute model analysis. Lastly we carry through a softwarearithmetic study of Instruction Radio, including: π/4DQPSK modulation anddemodulation, interpolation filter, timing synchronization and so on. The fruit of thesisset up a stable basis to implement Software Radio mobile Instruction station researchobject.
