Abstract: A pseudo-satellite transmitter includes a GPS unit, a transmission power control unit, and a plurality of antennas. The GPS unit generates a GPS signal of a pseudo-satellite. The transmission power control unit generates a plurality of GPS signals having different power levels based on the GPS signal generated by the GPS unit and a distance from a shadow area to the pseudo-satellite transmitter. Each antenna is configured to wirelessly transmit the GPS signals with different power levels output from the transmission power control unit to a corresponding one of a plurality of shadow areas according to the distance from the shadow area to the corresponding antenna.

Abstract: A method for reference signal generating in an ultra wideband (UWB) communication system which sends out and receives data by using at least two reference signals of predetermined frequencies. A first signal group, which comprises a local oscillation (LO) signal and a signal at a predetermined phase difference with respect to the LO signal, is generated. One among at least two intermediate frequency (IF) signals is selected for the adjustment of the frequency of the LO signals, and a second signal group, which comprises the selected IF signal and a signal at a predetermined phase difference with respect to the selected IF signal, is generated. Two mixed signals are generated from the first and the second signal groups, the mixed signals being mixed without overlap, and a reference signal is generated by adding the two generated signals.
