Abstract:
1. A device for inductive multi-injection on multiple conductors, intended for permitting an application of methods for increasing performance of a communications system on a medium made up of N conductors and a reference plane, the device is characterized in that the device is made up of: E signal inputs, where E is between 1 and N, for each one of a plurality of signals to inject in the N conductors; A inductive couplers, A being equal to or greater than twice the number of signal inputs E, where the number of inductive couplers A used in the device depends on a number of injection modes and on a number of conductors used by each one of the injection modes, and where a conductor of the N conductors passes through a gap in one of the A inductive couplers on one or more occasions; and E signal injection loops, each one of which provides a mode selected from a differential mode, a pseudo-differential mode and a common mode, wherein the E signal injection loops pass through the A inductive couplers located around the N conductors on which said E signal injection loops are going to inject current, and a direction in which the E signal injection loops traverse each of the A inductive couplers determines a direction of the current injected in each of the N conductors, wherein selectively a number of turns of each of the E signal injection loops on each of the A inductive couplers and a number of turns of each of the N conductors on each of the A inductive couplers is such that injections are achieved for the differential mode, the pseudo-differential mode and the common mode, in order to inject communications signals in up to N combinations of the N conductors and obtain injected signals that are orthogonal to each other.
