Patent ID: 7898999

Claim:
Method for exchanging signals via nodes ( 11 - 14 ) and comprising the steps of at a source node ( 11 ), processing a source signal ( 21 , 22 ) and transmitting the source signal ( 21 , 22 ) to a destination node ( 12 ) via a first signal route comprising an intermediate node ( 13 , 14 ) and via a different second signal route, with at least one signal route being a wireless signal route; at the destination node ( 12 ), receiving a first destination signal ( 31 ) corresponding with the source signal ( 21 , 22 ) and having followed the first signal route; at the destination node ( 12 ), receiving a second destination signal ( 32 ) corresponding with the source signal ( 21 , 22 ) and having followed the second signal route; at the destination node ( 12 ), processing and correlating the first and second destination signal ( 31 , 32 ) with each other; and in dependence of a correlation result, adjusting a process for processing a signal at a node ( 11 - 14 ) such that transmission of a future source signal is improved.
