"Operator to be used in a receiver of a spread spectrum modulation system of direct sequ0153u00eancia and search process of a signal from the received signals in the ideal receiverA system for spread spectrum sequ0153u00eancia directly.An explorer to be used in a receiver of a spread spectrum modulation system of direct sequ00b3u00eancia (DSSS) includes a code generator of pseudo noise (PN), to generate a PN code; U.M mixer to mix a received signal with the PN code generated by the PN code generator, an accumulator for accumulating a signal output despropagado mixer; a signal processor digitAIS for the control of the PN code generator in response to a command search and generate path information representative of the search results of the signal received within a corresponding windowThe command search using the results of acumulau00e7u00e0o by the accumulator; and a microprocessor for generating the command of search.Getting the information from the digital signal processor.And to determine a search window following according to the information that the route received digital signal processor of the results of the decision as a command to search.
