Design of a Software Defined Radio Channel Simulator for Mobile Communications: Performance Demonstration with DSRC for Different Vehicle Speeds

摘要

The reconfiguration scheme and channel algorithms of the software defined radio (SDR) channel simulator is designed for testing the base band transceiver of various mobile radio systems. The flexibility in selecting a combination of waveform and fading channel software modules and setting the system parameters is the main feature of the SDR channel simulator. An example of the SDR channel simulator implemented with the air interface standard of the dedicated short range communications (DSRC) system for different vehicle speeds is carried out to observe its performance and validate its correctness.
