  • Patent number: 8010051
    Abstract: A multi-path simulation system (100) includes a signal generator (10) generating a signal, a power divider (24) connected to the signal generator for dividing the signal into N attenuated sub-signals, N delay lines (26) connected to the power divider delaying the N attenuated sub-signals to simulate the delays resulting from the transmission of the signal in the N paths, P switches (28) connected to the delay lines selecting the attenuated sub-signals delayed by the delay lines, thereby generating selected signals, and a signal combiner (29) connected to the switches combining the selected signals into a single signal. The delay lines are respectively represented by transmission lines disposed on a printed circuit board. A length of the transmission line controls a distance of transmission of the signal. Wherein N is an integer greater than one, and P is an integer equal to or greater than one.
