Real-time Ultra-Wideband Channel Sounder

A new real-time Ultra-Wideband (UWB) channel sounder is introduced that allows the measurement of the time-variant radio propagation channel in the extreme wide band ranging from nearly zero to 5 GHz. The RF interface comprises of integrated digital circuits in SiGe technology. A Maximum Length Binary Sequence (MLBS) is used as transmit signal. At the receiver, fast track-and-hold and interleaved sampling is applied for data recording. The received signal is correlated with the reference by a DSP. Excellent timing stability, low power consumption and miniature size support synchronous multi-channel operation which is a prerequisite to build a Multiple-Input-Multiple-Output (MIMO) sounder.
