    Abstract: The present invention is a time vernier providing fine timing control of an input signal having coarse timing edges. The time vernier comprises a receiving means for receiving a value representing a desired time delay to be added to the coarse timing edge input. The desired time delay may have both fine and coarse delay aspects. The time vernier also comprises a first decoding means for decoding the fine delay aspect and generating fine delay control signals, as well as a second decoding means for decoding a coarse delay aspect and generating coarse delay control signals. A delay line is also included in the time vernier which has inputs to receive the input signal having coarse timing edges, the fine and coarse delay control signals, and a control voltage which automatically adjusts with temperature and power supply variations, so as to provide for temperature and power supply compensation. The delay line combines the fine and coarse delay signals to provide an output signal with fine timing edges. Furthermore, the architecture of the present invention enables an automated method of calibration in order to adjust fine and coarse delay elements for fabrication process variations and photolithography variations.

    Abstract: A minimum confidence level is applied to recognize a localizable wireless system debility from a debility which is invariant from place to place or which cannot be significantly distinguished from service performance levels of comparable mobile user terminals in the network as a whole. Reports received by the population of users of a service or product family are scored, aggregated, normalized, and averaged overall and for each geographic service area. A report is received from a particular end user and the customer operated wireless instrument and transformed into an individual user experience score over a length of time and breadth of locations. The reports provided by the population of users are transformed into a population experience score that reflects usage in the same time and locations reported from the wireless instrument of the particular end user. Various potential causations are considered and those which exceed a minimum level of confidence are presented.

    Abstract: Disclosed is a method of and apparatus for increasing the capacity of a wireless communication system. This is accomplished by having users that can support a higher than base modulation order be required to do so under predetermined conditions such as electrical distance from a base transceiver station (BTS) antenna to a user, the reception of data in a high speed burst (HSD) and the like. The same digital processor apparatus that may be used to provide a base order modulation scheme may be reprogrammed in a more complex fashion to provide signal processing at the higher modulation rate for any given user channel.

    Abstract: The present invention is directed to a delay line for providing fine timing adjustment on subsequent edges of an input signal. The delay line comprises a plurality of delay elements for fine tuning the position in time of the timing edges of the input signal. Each delay element has a data input and data output where the data output is connected to the subsequent delay element's data input, thereby forming a delay line with delay elements connected in series. This implementation facilitates the addition of fine increments of delay to be added to the input signal and thereby enable fine tuning of timing edges. Also, included is a wired-OR multiplexor having data inputs connected to the data outputs of the plurality of the delay elements and a control input to select a particular data output to thereby provide an output signal having delayed timing edges.
