Abstract (en)
[origin: WO9917461A2] The invention concerns a method and a device for avoiding interference in a transmission system operating with chirped frequency modulation. The invention is characterised in that a signal p is expanded in a transmitting station (TX), then compressed again, after being transmitted in a receiving station (RX1; RX2; RX3). In the latter, the expanded impulse pe is routed to a filter (SAW3, SAW4) whereby are formed partial signals (s1, ..., sn) for each of the n frequency bands (fb1, ..., fbn). At least the partial signals pertaining to a transmission channel are controlled relative to operating conditions, then partially or entirely added before being gathered to form an entire compressed signal pk.
