Title:
How to reduce the glare of a receiver which receives a signal from a transmitter
Document Type and Number:
Japanese Patent JP6023707
Kind Code:
B2
Abstract:
The present invention relates to a method of reducing the glare of at least one receiver within a positioning system, the system including a plurality of emitters, each emitter emitting signals modulated by one and the same code whose autocorrelation function exhibits a main peak and at least one white zone in which the autocorrelation function is a minimum, the signals for each emitter includes a first signal modulated by the code and a second signal out of phase with respect to the first signal, the second signal being modulated by the code which is delayed with respect to the code modulating the first signal, and a receiver, the latter being configured so as to detect signals emitted by the emitters and implementing, for the tracking of the first and second signal emitted by one of the emitters, a local signal modulated by the code.
