An SDR Based Channel Sounding Technique for Embedded Systems

An SDR Based Channel Sounding Technique for Embedded Systems

 Abstract:

This paper presents a low cost OFDM based channel sounding technique which can be implemented on a low power embedded system. The technique is first used to measure the channel of an indoor environment and is validated by comparison with a VNA and a ray-tracing simulator. We then show its usage in two interesting situations. Finally, we conclude the paper by giving the advantages and drawbacks of the technique and propose some solutions for improvement.
