摘要： A multi-clock matched filter for receiving signals with multipath. The signals may be modulated with a spread-spectrum spreading sequence, or other analog or digital signal. A number of signal registers store digital samples of the received signal. The gating of digital samples into each of the signal registers is controlled by a separate clock timing. The timing sequence may be derived from a common clock. A multiplexer sequentially selects each of the signal registers, and passes the respective content of each signal register to a matched filter. A number of delay-locked-loop circuits track each of the multipath signals, and generate the timing sequence for gating signal registers.

摘要： A subsystem and method for combining a spread-spectrum signal arriving from a plurality of paths. A header-matched filter detects each match of a header-chip-sequence signal with a first impulse response and, in response to the detection, outputs a header-detection signal having a header amplitude and a respective chip location. A data-matched filter detects, at the respective chip location of each header-detection signal, a respective data-chip-sequence signal and outputs a data-detection signal having a data amplitude. A combiner multiplies the header amplitude of each header-detection signal and the data amplitude of the respective data symbol to generate a plurality of weighted elements for each data symbol. The combiner then adds the plurality of weighted elements for each data symbol as a sum signal of the respective data symbol.

摘要： A spread-spectrum receiver for time sharing a correlator for simultaneously receiving a plurality of parallel spread-spectrum signals. A combined multiplicity of symbols includes a multiplicity of symbols, simultaneously occurring during a symbol-time duration, from a plurality of spread-spectrum signals. A demultiplexer demultiplexes a sequence of the combined multiplicity of symbols into a plurality of symbol registers. Each of the symbol registers stores the chip-sequence signals corresponding to the combined multiplicity of symbols which were sent to the particular symbol register. A multiplexer selects a symbol register, other than the symbol register selected by the demultiplexer. The multiplicity of chip-sequence signals stored in the selected symbol register by the multiplexer are compared by a comparator with a multiplicity of replicas of the chip-sequence signals used to generate the spread-spectrum signals.

摘要： A multipath-combining subsystem for receiving a spread-spectrum signal arriving from a plurality of paths. A header-matched filter detects each match, within each path, of a header-chip-sequence signal with a first impulse response and outputs a header-detection signal having a header amplitude and a respective chip location. A data-matched filter detects at the respective chip location of each header-detection signal, a respective data-chip-sequence signal and outputs a data-detection signal having a data amplitude. A combiner multiplies the header amplitude of each header-detection signal and the data amplitude of the respective data symbol to generate a plurality of weighted elements for each data symbol. The combiner then adds the plurality of weighted elements for each data symbol as a sum signal of the respective data symbol.
