UWB time domain channel sounder

This paper describes a time domain channel sounder based on pseudorandom binary sequences. The channel sounder system consists of several off-the-shelf laboratory instruments connected together and controlled from PC. Frequency band of interest is the unlicensed ultra wide band, 3-11 GHz. The system's parameters are discussed and compared to conventional solution, which uses vector network analyzer (VNA). Crucial feature of the proposed system is fast measurement speed. Example measurements are provided and compared to the measurements performed using the VNA.
