Ultra wideband (UWB) spatio-temporal propagation measurements have been carried out mostly using virtual array antennas and a vector network analyzer (VNA). The VNAs transmit only sinusoidal signals at the discrete frequencies, and thus a number of snapshot is limited to unity. To remedy this drawback, we propose a UWB channel sounder using orthogonal frequency division multiplexing (OFDM) signals. A prototype has been developed to be combined with conventional virtual array antennas. It performance was compared with a VNA-based channel sounder and a pseudo-noise-based one in an artificial multipath environment (generated by using a microwave hybrid and a coaxial cable with the end shortened) and in a radio anechoic chamber (1-, 2-, and 3-wave environments). Well agreed results were obtained to validate the design and the usefulness of the OFDM-based channel sounder. |
