Abstract: 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.

Abstract: A system and method for multi-radio control unifies disparate radio technologies and communication protocols and abstracts them such that a user of a personal electronic device having a plurality of disparate radios is not required to know or understand the radio technology needed to connect to a remote wireless device or service. An intermediate layer receives requests from a user interface application, generates specific driver commands to each radio, and returns information received from each radio to the user interface application module. A user interface application module initiates a search for available remote wireless devices, provides the user with information regarding the available remote wireless devices, and establishes a connection to an available remote wireless device in response to a user selection. The user interface application module also presents notifications to the user, and also handles disconnect requests and security credential dialogs.

Abstract: In a wireless communication system, a portable device and an in-vehicle device wirelessly communicate with each other by a spread spectrum method. The in-vehicle device transmits a synchronization signal indicative of a reference period to the portable device. The in-vehicle device performs code acquisition for only a portion of a spread wireless signal received from the portable device. The portion has a starting point in a search period from a search start point to a search end point. The search start point is identified based on the reference period and a predetermined first correction time. The search end point is identified based on the reference period and a predetermined second correction time.

Abstract: A configurable all-digital coherent demodulator system for spread spectrum digital communications is disclosed herein. The demodulator system includes an extended and long code demodulator (ELCD) coupled to a traffic channel demodulator (TCD) and a parameter estimator (PE). The demodulator also includes a pilot assisted correction device (PACD) that is coupled to the PE and the TCD. The ELCD provides a code-demodulated signal to the TCD and the PE. In turn, the TCD provides a demodulated output data signal to the PE. The PACD corrects the phase error of the demodulated output data based on an error estimate that is fed forward from the PE. Accumulation operations in the ELCD, TCD, and PE are all programmable. Similarly, a phase delay in the PACD is also programmable to provide synchronization with the error estimate from the PE.

Abstract: A data transceiver module for digital data communications in a portable hand-held data terminal has multiple data spread spectrum modes which include direct sequence and frequency function modulation algorithms. The transceiver module has multiple user or program configurable data rates, modulation, channelization and process gain in order to maximize the performance of radio data transmissions and to maximize interference immunity. Various module housings, which may be PCMCIA type, are able to be mated with a suitably designed data terminal. Media access control protocols and interfaces of multiple nominal operational frequencies are utilized. Wireless access devices in a cell based network each consider a variety of factors when choosing one of a plurality of modes of wireless operation and associated operating parameters. Such selection defines a communication channel to support wireless data, message and communication exchanges. In further embodiments, the wireless access devices also support a second channel, a busy/control channel, for managing communication on the main communication channel and to overcome roaming and hidden terminal problems. Roaming terminal devices are also configured to support the dual channel design. Such configuration in both circumstances may involve the use of a multimode radio that is timeshared between the two channels or two radios, one dedicated to each channel.

Abstract: A correlation module includes a plurality of first functional modules, a plurality of second functional modules, a plurality of function adjust modules, a summation module, a correlation value register, and a correlation evaluation module. The plurality of first functional modules is operably coupled to perform a first function upon a first corresponding pipelined data element to produce a first corresponding value. The plurality of second functional modules is operably coupled to perform a second function upon a second corresponding pipelined data element to produce a second corresponding value. The plurality of function adjust modules is operably coupled to selected ones of the plurality of first functional modules and to selected ones of the plurality of second functional modules. The summation module is operably coupled to sum the plurality of first corresponding values, the plurality of second corresponding values, and a previous correlation value to produce a current correlation value. The correlation evaluation module is operably coupled to compare the current correlation value with a correlation threshold to determine whether current pipelined data correlates with the expected pattern of the training sequence.
