摘要： A symbol detector for frequency modulated (FM) symbols includes a section determiner, a direction of movement determiner and a data symbol determiner. The section determiner receives a sample of in-phase and quadrature signals associated with a baseband transmitted FM symbol and determines the section value of a unit circle in an in-phase—quadrature coordinate system in which the sample lies. The direction of movement determiner receives the section value of a current sample and the section value of a neighboring sample and generates a positive direction of movement value if the direction of movement along the unit circle from the neighboring sample to the current sample is counterclockwise, a negative direction of movement value if the direction of movement is clockwise and 0 otherwise. The data symbol determiner receives the direction of movement values and decodes the transmitted FM symbol by masking N direction of movement values.

摘要： A pilot acquisition unit for code division multiple access (CDMA) communication systems is provided which includes a fast Hadamard transform (FHT) unit and a pre-Hadamard processing unit. The FHT unit determines the quality, in accordance with a metric, of each of a set of possible pseudo-random number (PN) loadings and the pre-Hadamard processing unit generates a vector u per set of PN loadings. The vector u defines a quality metric of a received pilot signal with the set of possible PN loadings, the pre-Hadamard processing unit providing the vector u to the FHT unit.

摘要： The today's mobile handheld and portable devices become slim and thin while need to communicate with other devices and accessories that are attached or at very short range. The interface (contact based physical connector) becomes a real challenge and unreliable to the consumer that needs to attached and detach its device several times a day.It is an object of the present invention to provide system and method of replacing a contact based physical interface (connector) with very short range wireless (contactless) interface. This technique is called “contactless virtual connector” or CVC.The method of the present invention is based on a transmission of a very low power and wideband RF signal. The new innovating mechanism replaces the traditional physical connector with new radiated signal technique that consumes very low power and may be cost competitive with the today's physical connectors.The innovated contactless technology may be used for small flexi-cable replacement in the handheld devices as flip or slider based handheld devices.Although the contactless technique is a wireless based solution, yet, the link may be well secured at the Physical layer when the near-field technique is used.
