Abstract: A method and apparatus for adaptively despreading a direct sequence spread spectrum signal. The direct sequence spread spectrum signal is provided to transversal filter (101). The output of filter (101) is despread by despreader (120) to provide a soft symbol determined by symbol estimator (122). The soft symbol is provided to decision circuit (124) which generates an error corrected version of the soft symbol data, referred to as a hard symbol. The value of the hard symbol is subtracted from the soft symbol by subtractor (126) to generate an error symbol. The error symbol is then used to compute tap values of the transversal filter by means of an LMS algorithm employed by tap adapter (103).

Abstract: A method and apparatus for paging a concentrated subscriber system (113) for wireless local loop within a cellular telephone system is described. Within a mobile telephone switching office (MTSO) (104) a visitor location register (130) is generated in which a subscriber unit identification number (SUIN) for every subscriber unit registered within the area of coverage is stored along with corresponding telephone number, last cell site, and concentrated subscriber system (CSS) status information. The SUIN can correspond to the electronic serial number (ESN), mobile identification number (MIN), or other unique identification code assigned to each subscriber unit (112). When a call directed to a subscriber unit having a particular telephone number is received the corresponding SUIN, CSS status information, and last cell site information of that subscriber unit are determined using the visitor location directory. In response to this determination a paging code is calculated in various manners depending on the resulting CSS status information of the subscriber unit being paged. If the subscriber unit being addressed is part of a CSS, the paging code used to generate the paging message is calculated in a first manner such that it is the same for each subscriber unit within a particular CSS. If the CSS status information indicates that the subscriber unit being paged is not part of a CSS the paging code is calculated in a second manner such that it is different for each subscriber unit. A set of paging parameters are then calculated using that paging code which in the preferred embodiment include a CDMA channel, a paging channel, and a paging slot. The page message is then transmitted in accordance with those paging parameters. In the preferred embodiment the page message generation process using the paging parameters is the same as that of the prior art cellular system in order to maintain maximum compatibility with those prior art systems.

Abstract: Method and apparatus for generating orthogonally encoded communication signals for communication system subscribers using multiple orthogonal functions for each orthogonal communication channel. Digital data symbols for signal recipients are M-ary modulated using at least two n-length orthogonal modulation symbols, which are generally Walsh functions normally used within the communication system. These symbols are provided by a modulation symbol selector (124) typically from one or more code generators (126, 128), and the modulation is such that M equals a product of a total number of orthogonal functions and the number used to generate individual modulation symbols. Each group of log M encoded data symbols from data processing elements (100, 102) are mapped into one modulation symbol using the modulation symbol selection element (124) according to their binary values. In some embodiments, a fast Hadamard transformer is used for symbol mapping. The resulting communication signals are demodulated by correlating them with the preselected number of orthogonal functions, in parallel, and demodulating the results into M energy values representing each orthogonal modulation symbol. The energy values are mapped into energy metric data using a dual maximum metric generation process. The correlation and demodulation can be accomplished using at least two sets of N correlators (142), N being the number of functions used, and applying correlated signals to one demodulator for each set of correlators (144). Each demodulator outputs M energy values representing each of the M mutually orthogonal modulation symbols, which are then combined into a single set of M energy values. In further configurations, coherent demodulators (172, 174) can be used to produce amplitude values for received signals which are then combined (178) with dual maximum metric results (170) to produce composite metric values for data symbols (178).

Abstract: A method and apparatus for displaying, to the driver of a vehicle (12, 14), an introductory or other portion of messages received by a mobile communications terminal (50) of the vehicle. The message display method may be implemented in a system which includes one or more vehicles (12, 14) in communication with a central control station (18). At least one of the vehicles (12, 14) is equipped with a mobile communications terminal (50) for communication with the central control station (18). In a preferred implementation, the mobile communications terminal (50) is coupled to an internal data link (92) of the one vehicle, to which is also connected a display device (102) in view of the vehicle driver. A first message packet is generated, at the central control station (18), for use by the vehicle driver. The first message packet is then transmitted from the central control station (18) and received by the mobile communications terminal (50). In a preferred embodiment, an introductory or other portion of the first message packet is provided to the display device (102) by way of the internal data link (92). This advantageously allows the vehicle driver to be apprised of the contents of incoming messages even without direct access to the mobile communications terminal (50).

Abstract: The method and apparatus of the present invention improve the immunity to interference of a radio receiver. The power level of a received signal is detected. If the power level meets or exceeds a predetermined power threshold, the low noise amplifier (703) is by-passed (730), thus increasing the intercept point of the receiver components. Alternative embodiments include the use of an RF power detector (105) to control the front-end gain (110) as a function of jammer power. In lieu of a switchable RF gain block (730), several methods of continuous gain control are proposed. Continuous gain control allows the interference suppression and sensitivity of the receiver to be adjusted at lower signal levels than the switchable gain block. A method of the present invention adjusts the input gain by a predetermined amount (1601). The receiver processing measures the gain change in the IF signal power (1605). If the change is less than the predetermined amount (1610), the CDMA signal and jammers are below the noise floor and, therefore, the gain is increased (1615). If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products (1620). This process is used until the receiver is operating at the best compromise between interference and noise figure.
