摘要： An audio jack includes a rectangular housing including a body including a rear first compartment and a hole extended from a front face to the first compartment, and an insulate plate secured to a top of the body; a plurality of contacts provided in the housing and including first, second, third, fourth, and fifth contacts each including a flexible portion and an upright solder portion; a light emitting element provided in the first compartment and aligned with the hole and including legs inserted through the first compartment; and a shell secured onto the housing. Inserting a first plug into the hole until the contact assembly is electrically connected with the plug will effect an analog signal transmission. Inserting a second plug into the hole until its head is electrically connected with the light emitting element will effect a digital signal transmission. The plate together with the shell can provide a double shield.

摘要： Midamble codes, acting as channel estimation, and information data, as well as system information, will be sent to the joint cell detector. Midamble codes are sent to the estimator of adjacent cell, as well as that of its own cell. As a matter of fact, channel response is sent to channel noise-depressed modules to be depressed. Then the depressed channel is sent to channel window activation detector to receive first activation detection, to see whether the channel windows are activated. Channel response, after detected by channel window, will be sent to multi-user jointed detection unit together with information data. The soft bit information, after having been demoduled or detected, will be transmitted to the following Transport Channel Decoding (TrCH) modules and Channel Decoding (CC) modules. This invention solves the technical problems, that is, interferences received by the user equipments in inter-frequency network from its own cell and the adjacent cells, and to combat the problems of low capacity and handovers.

摘要： The present invention provides systems and methods for faster acquisition and more stable tracking of spread spectrum signals with lower computational load requirements. Instead of the present day practice of using only the Prompt correlator, the systems and methods of the invention use the sum of the powers of all the correlators of a channel to determine the acquisition or tracking of the signal. These systems and methods improve the signal acquisition speed resulting in a reduced Time-To-First-Fix (TTFF). Further, these systems and methods improve the acquisition and tracking sensitivity of the receiver.

摘要： A technique is provided for automatic frequency offset correction in a wireless communication system. After demodulating and decoding a received signal in a receiver, channel estimation is also performed. The technique further includes re-encoding and re-modulating the decoded and demodulated signal with a coding and modulation scheme different from the received signal. The signal is reconstructed signal on the basis of the re-encoded and re-modulated signal and estimated channel characteristics. A frequency error is estimated based on the reconstructed signal and the original received signal. A threshold for a comparator is determined on the basis of the estimated offset amount determined by the comparison threshold and the estimated frequency offset.

摘要： Balun transformers are described wherein multiple transformer loops are implemented in a stacked design with the primary and secondary loops overlying one another. By aligning the loops in a vertical direction, instead of offsetting the loops, the area of the device is reduced. Multiple transformer loops are nested on each level, and the transformer loops on a given level are connected together using a crossover located on a different level.
