An apparatus for determining a coincidence of a position with a reference position, wherein radio signals from fixedly positioned radio transmitters can be received at the position, having a provider for providing properties of the radio signals of the fixedly positioned radio transmitters at the position, wherein the provided properties of the radio signals include transmitter identifications identifying the radio transmitters, a separator for separating the radio transmitters into a first number of radio transmitters previously recorded transmitter identifications of which at the reference position are identical with transmitter identifications provided at the position, and into a second number of radio transmitters previously recorded transmitter identifications of which at the reference position and transmitter identifications provided at the position are different, and a determiner for determining a measure of matching for the position on the basis of the provided properties of the radio signals, wherein both properties of the first number of radio transmitters and properties of the second number of radio transmitters are taken into account in the determination of a measure of matching, and wherein the properties of the first number of radio transmitters and the properties of the second number of radio transmitters enter the measure of matching differently.

A method is provided for determining a scan strategy to receive data for a digital unit associated with an electronic support measure receiver. The receiver scans a surrounding environment to detect and receive emitted signals while utilizing the digital unit to improve emitter identification. The digital unit is provided with the data according to requirements of digital signal processing algorithms implemented by the unit.

A method and system for identifying a distributed model for a nonlinear system represented by a block diagram. The distributed model identification can be achieved by first replacing all signal links across the block diagram with elastic links by augmenting each input port of a plurality of blocks with a signal generator that produces a replacement signal value (sig) for the value received by each of the plurality of blocks. Thereafter, the difference between the received value and the replacement signal values can be calculated and outputted as an auxiliary signal to control elasticity of the elastic links. Then, instead of global identification of the block diagram parameters, i.e. treating the diagram as a whole, the block parameters are identified locally based on the local data. Simultaneously, the auxiliary output signals are forced to vanish. Consequently, the solution found is also a solution to the global identification method.

The invention relates to a method and an apparatus for position replacing and identification code changing of emitters of a TPMS system. The apparatus comprises a multimedia playing device and a receiver. The multimedia playing device outputs an emitter transposition protocol frame to the receiver when receiving an emitter position replacing instruction and selection of two emitters in need of replacing of positions. The multimedia playing device outputs an identification code changing protocol frame to the receiver when receiving an identification code changing instruction and a changed emitter identification code from an input device. A memory of the receiver stores a plurality of emitter positions and identification codes. Positions of the two emitters in the memory are replaced according to the emitter transposition protocol frame, and the identification code of one emitter in the memory is changed according to the identification code changing protocol frame. Compared with conventional operation modes, a scheme provided by the invention has the advantages of low cost and simplified operation.
