<p>The device has a splitter (421) to split an interfered global positioning system signal into two signals, each propagating in a different channel. A summer (423) sums the two channel signals. A surface acoustic wave filter (424) and a phase shifter (425) fix the phase shift between the signals propagating in the two channels such that the signals are in opposite phase during their summation. The surface acoustic wave filter (424) and the phase shifter (425) are situated in one of the two channels to phase shift the signal propagating in the channel with respect to the other signal. Independent claims are also included for the following: (A) a positioning device compatible with a global positioning system (B) a process for rejection of an interfering signal in a spread spectrum signal.</p> |
