摘要： A modem is configured for demodulating a communication signal associated with a unique code-division multiple access (CDMA) code. The modem includes an adaptive matched filter and a vector correlator. The vector correlator generates filter coefficients for the adaptive matched filter based on signal distortion determined by the vector correlator. The vector correlator has a processing capacity of at least eleven chips whereby the vector correlator compensates for a known phase distortion and for multipath distortion ascertainable within its processing capacity. The adaptive matched filter processes communication signals with the unique CDMA code using coefficients generated by the vector correlator.

摘要： In a method of transmitting electromagnetic signals between a stationary transmitting/receiving station and a transmitting/receiving station in a magnetic levitation train vehicle, the magnetic levitation train vehicle is guided on a travel path that includes stator laminations arranged on its underside. Signals to be transmitted are coupled from a travel-path-side coupling-in point connected with the stationary transmitting/receiving station into the stator laminations of at least one travel path side of the magnetic levitation train, and are decoupled from a vehicle-side coupling-out point connected with the transmitting/receiving station in the vehicle out of the stator laminations and vice-versa. The stator laminations are used as a transport medium of signals between the respective coupling-in and coupling-out point.

摘要： A duplexer for a communication device having a transmission unit, a reception unit and a shared antenna. The shared antenna transmits a portion of a transmission signal provided by the transmission unit and receiving a reception signal. The duplexer generates a leakage signal from the transmission unit toward the reception unit. The leakage signal being added to the reception signal. The duplexer comprises a first signal path between the transmission unit and the reception unit. The first signal path comprises a filter unit filtering the reception signal. The filtering unit provides a filtered signal to the reception unit. The duplexer further comprises a second signal path between the transmission unit and the reception unit. The second signal path comprises a cancellation unit which receives a sample of the transmission signal and produces a compensation signal. The injection of the compensation signal to the first signal path substantially reduces the leakage signal, thereby producing a substantially leakage-free reception signal.

摘要： The invention relates to a method to synchronise a multi-carrier transmission system wherein a time misalignment between a transmitter and a receiver is determined through an average of at least two pilot tones phase errors (nulli) weighted in accordance with the noise affecting each pilot tone transmission. Such method is characterised in that, when the noise affecting a pilot tone (38, 40) reaches a predetermined level, the pilot tone function is reallocated from this pilot tone (38, 40) to another carrier (42, 44) and/or this pilot tone weight is reduced.
