摘要： There is provided an address generation apparatus for one of an interleaver and a deinterleaver in a Wideband Code Division Multiple Access (W-CDMA) system. The apparatus includes an address pair generator for generating an address pair (n, P(n)) in real-time for one of an interleaver operation and a deinterleaver operation that includes inter-row permutation and intra-row permutation. The address pair (n, P(n)) is generated such that, for the interleaving operation, data to be interleaved are read out from the at least one memory device using the P(n) and interleaved data are written into the at least one memory device using the n. Further, the address pair (n, P(n)) is generated such that, for the deinterleaving operation, data to be deinterleaved are read out from the at least one memory device using the n and deinterleaved data are written into the at least one memory device using the P(n).

摘要： There is provided a method for generating an error signal for an automatic frequency control (AFC) loop in a Code Division Multiple Access (CDMA) system. Sign information relating to phase differences in received pilot signals is accumulated. In one embodiment, the accumulated sign information is compared against predetermined threshold levels. The error signal is generated when at least one of the predetermined threshold levels is satisfied. In a second embodiment, the accumulated sign information is decimated. An output of the decimating step is utilized as the error signal for the AFC loop.

When bi-directional prediction coding at the coding end, firstly the given forward candidate motion vector of the current image block is obtained for every image block of the current B-frame; the backward candidate motion vector is obtained through calculation, and the candidate bi-directional prediction reference block is obtained through bi-directional prediction method; the match is computed within the given searching scope and/or the given matching threshold; finally the optimal matching block is selected to determine the final forward motion vector, and the backward motion vector and the block residual. The present invention achieves the object of bi-directional prediction by coding a single motion vector, furthermore, it will not enhance the complexity of searching for a matching block at the coding end, and may save amount of coding the motion vector and represent the motion of the objects in video more actually. The present invention realizes a new prediction coding type by combining the forward prediction coding with the backward.

摘要： One illustrative method for use by a host server in pushing messages to a mobile communication device involves the steps of causing a message to be sent to a relay network for delivery to the mobile communication device through one of a plurality of wireless communication networks which are communicatively coupled to the relay network; receiving, from the relay network, a result message when the mobile communication device is unavailable to receive the message through the wireless communication network, the result message comprising a message identifier which uniquely corresponds to the message; maintaining storage of the message in memory accessible by the host server after the result message is received; receiving, from the relay network, a status message which indicates that the mobile communication device is available to receive the message when the mobile communication device is available to receive the message through the wireless communication device; and causing the message to be sent again to the relay network for delivery to the mobile communication device in response to receiving the status message. During the unavailability of the mobile device, the relay network refrains from maintaining storage of the message in memory of the relay network.

摘要： A wireless telephony communications system includes at least one macro cell for communicating both voice and data with a mobile communications device across a first wireless link and at least one micro cell for communicating data with the mobile communications device across a second wireless communication link. Each micro cell communicates signaling information through the macro cell via a wireless link to a control element that manages the micro cells. Using a wireless link to communicate signaling between each micro cell and the control element in the UMTS system eliminates the need for a wired back haul link, thereby reducing access costs.
