Abstract: The present invention a system and method are provided for performing an inter-frequency search with reduced loss of link frames in a CDMA system. The CDMA system includes a base station (20) and a mobile station (50). The mobile station (50) has a searcher (164), which searches for pilot channels. The signal strengths of these pilot channels are then reported to the base station (20). This searching results in erased portions of a data frame (238). After the signal strengths are reported to the base station (20), the mobile station (50) informs the base station (20) of the parameters related to the search. These parameters may include the frame of the search, the start position of the search, and the length of the search. The mobile station (50) and the base station (20) then replaces the erased portions of the frame with corrective data such as soft zeros.

Abstract: The present invention relates to systems and methods that facilitate compensating for intersymbol interference (e.g. due to non-nyquist filtering) in Code Division Multiple Access (CDMA) systems (e.g., IS 95 and IS2000 systems). The subject invention employs equalization filters (e.g., T-spaced equalizers) at fingers of a RAKE receiver. By effecting such equalization filtering at a downstream point in a receiving system, e.g., at the fingers of the RAKE receiver, the filters can be run so as to operate at lower rates as compared to conventional systems where filtering is effected upstream where time is not necessarily known thus requiring equalization filters to operate at significantly faster rates (e.g., 2× or 4× expected chip rate). Accordingly, as compared to conventional systems where the matching filters often are of substantial complexity (e.g., >80 taps) the present invention provides for less complex equalization filters thereby reducing overall system complexity and cost.

Abstract: A method detects an absence of a transmitted frame in a wireless communications system that operates with a discontinuous transmission (DTX) protocol between a transmitter and a receiver. The method includes decoding a received signal over a frame period to determine a cumulative metric; normalizing the cumulative metric and comparing the normalized cumulative metric to a threshold for determining whether the frame was a transmitted frame or a non-transmitted frame. The determined cumulative metric may be a maximum cumulative metric or a zero state cumulative metric. The wireless communications system may be a CDMA system, the receiver may be contained within a mobile station, and the determination of whether the frame was a transmitted frame or a non-transmitted frame can be employed, as one non-limiting example, during execution of a power control algorithm.

Abstract: A method for synchronization of a receiver to a direct sequence spread spectrum (DS-SS) signal in a telecommunications system. A verification process is performed in the receiver upon initial detection of a first DS-SS signal prior to attempting synchronization to a second signal. In the verification, a window search is performed in a window centered on the PN phase of the initially detected first signal. A number K of search passes are made, each on M PN offsets. At least one parameter for each of the K window search passes is saved. The at least one parameter from each pass is then processed according to a predetermined algorithm. Based on the results of the algorithm, a decision is made as to whether or not to attempt synchronization to the second signal or to restart the search.

Abstract: Early and on-time signals are generated from a received CDMA signal for each PN code phase being searched, and the early and on-time signals are each divided into a number of subdwells sequentially in time. A correlation is then performed for each PN code phase search, on subdwells of the early and on-time signals for that PN code phase in a staggered manner in time, by alternating the correlation between the early and on-time signals during each sequential subdwell correlation. A detection statistic for the PN code phase is then generated from the correlation result. In an embodiment of the invention, two PN code phases are searched simultaneously by staggering the subdwell correlations in an alternate fashion between the early and on-time signals, so that each PN code phase uses a different set of subdwell correlations. In an alternative embodiment, a single PN code phase is searched by alternating the correlation between the early and on-time signals during each sequential subdwell correlation.

Abstract: A process for intramolecularly condensing a polyamic acid composition containing an NLO compound to form a polyimide host matrix composition containing as a guest the NLO compound, which process includes the step of uniformly heating the polyamic acid composition, in the absence of a solvent or diluent, to a temperature at which the intramolecular condensation will occur without thermal degradation of the NLO compound, so that the temperature differential within the polyamic acid is below that which will produce localized thermal degradation temperatures, until the intramolecular condensation of the polyamic acid composition to the polyimide host matrix composition is substantially complete. Polyimide host matrix compositions containing guest NLO compounds prepared by the inventive process are also disclosed, wherein the NLO compounds have external field-induced molecular alignments.
