  journal={IEEE Trans. Instrumentation and Measurement},
For the real-time identification of the time-variant, directional structure of the mobile radio channel impulse response, a broadband vector channel sounder is described. The measurement procedure relies on periodic multi-frequencyexcitation signals, correlation processing and joint delay-azimuth superresolution based on the ESPRIT algorithm. The underlying signal model is developed and the different possibilities of ESPRIT application are discussed. Problems of imperfect r ceiver and antenna… CONTINUE READING
