摘要： A method for detecting spread spectrum signal spread code synchronization for enhancing sensitivity of the spread code synchronization detection. A method for detecting synchronization of a spread code, for a spread spectrum signal created by data having a multiple of one cycle of the spread code as a bit transition cycle and spectrum−spread by the spread code. Per unit time which is a multiple of one cycle of the spread code and which is shorter than the bit transition cycle, results of correlation calculations between the spread spectrum signal and the spread code are linearly added, so as to obtain a linear addition correlation calculation result. An absolute value is calculated for each linear addition correlation calculation result obtained per unit time. Absolute values of the linear addition correlation calculation results of plural unit times are added. A correlation point is detected from the sum of the absolute values obtained.

摘要： A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit is in an "active state" during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The integration interval of the searches performed is based on the measured signal strength of another base station. The search engine performs searches using the integration interval. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases.

摘要： Demodulator architectures for processing a received signal in a wireless communications system. The demodulator includes a number of correlators coupled to a combiner. Each correlator typically receives and despreads input samples (which are generated from the received signal) with a respective despreading sequence to provide despread samples. Each correlator then decovers the despread samples to provide decovered "half-symbols" and further demodulates the decovered half-symbols with pilot estimates to generate correlated symbols. The decovering is performed with a Walsh symbol having a length (T) that is half the lenght (2T) of a Walsh symbol used to cover the data symbols in the transmitted signal. The combiner selectively combines correlated symbols from the assigned correlators to provide demodualted symbols. One or more correlators can be assigned to process one or more instances of each transmiteed signal. The pilot estimates used within each assigned correlator to demodulate the decovered half-symbols are generated based on the signal instance being prcessed by that correlator.

摘要： A spread-spectrum sliding matched-filter searcher system comprises a partial matched-filter (201) that receives the input spread-spectrum signal (101). The searcher matches samples of the input signal with a tap length m of the reference code (111) and produces a first correlation value. The first correlation value is compared to a first threshold. When it equals or exceeds the first threshold, the first correlation value is integrated (202) to produce a second correlation value. This second value is compared (203) with a second threshold, which if met signifies the detection of the multi-path signal. The process is repeated until all signification multi-path signals are detected. The design of the present invention is flexible in nature because the searcher can be programmed to act like a matched-filter, a correlator, or a combination of both while significantly improving the search time and reducing the amount of hardware and complexity characteristic of a matched-filter.

摘要： A technique for correlating a stream of signal sample values with a predetermined binary code having a plurality of binary code bits is disclosed. The technique is realized by forming precombinations of groups of the signal sample values in the stream, and then temporally ordering the precombinations. Particular ones of the temporally ordered precombinations are selected based upon particular combinations of the plurality of binary code bits. The particular selected ones of the temporally ordered precombinations are then combined to form a correlation.

摘要： Methods and systems for time synchronizing a receiver to a spread spectrum signal are described. Exemplary embodiments of the present invention provide for at least a two step process in which, at a first step, a number of candidate synchronization frequencies or timings are identified, followed by confirming one of the candidates as a correct synchronization state at a second or final step. According to the present invention, the confirmation step may be performed at the same time as the step of identifying further candidates by processing the same received signal samples in different ways.

摘要： A spread spectrum signal is processed after it is sampled at a selected sampling rate and tuned to a center frequency lower than the sampling rate and greater than zero. The signal is multiplied against a reference signal (133) to produce a corresponding product output (135), and an accumulation output (137) is formed by combining the product output (135) with a phase-shifted version of the accumulation output (141).
