Simultaneous measurement of multiple impulse responses with a single receiver

This paper presents a method for the simultaneous measurement of multiple impulse responses with a single receiver. For UWB measurements multiple impulse responses are usually determined at different times. Here, an approach is investigated, which employs preferred pairs of maximum length sequences (m-sequences) having a low cross correlation function. Therefore, a measurement system is built capable of generating and sampling two m-sequences at 400Mb/s. Since the m-sequences are not decoupled perfectly, a method for the error correction is shown.
