摘要： Searcher hardware is multiplexed to perform simultaneous searches in either an IS-95 CDMA mode or a GPS mode. In the IS-95 mode, the search hardware is time-multiplexed into a number of searcher time slices, each of which can generate a PN sequence to despread a data sequence. In the GPS mode, the search hardware is configured as a number of distinct GPS channels, each of which can generate a Gold code sequence for tracking a GPS signal from a particular GPS satellite. This configuration allows the searcher to perform multiple GPS signal searches simultaneously. Signal searching in both IS-95 and GPS modes is performed at significantly higher speeds compared to conventional searcher hardware. Moreover, the search hardware can be dynamically configured to operate in either the IS-95 or the GPS mode, eliminating the need for dedicated circuitry for each mode of operation.

摘要： A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.

摘要： A flexible and monolithic rake receiver apparatus, method, or computer-readable medium to decode a multi-path spread-spectrum signal to produce symbols. The rake receiver includes an input data double buffer, an interpolator, a correlation engine and a coherent accumulator. The input data double buffer collects input data during a current time-share period. The input data is interpolated and rotated, producing despread data and descrambled data. A coherent accumulation is performed resulting in symbols from the despread and descrambled data.

摘要： A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.
