System for measuring the time of signal arrival in the DS-CDMA signal correlation-type receiver

摘要

the subject of the invention is a system for measuring time arrival signal in the correlation receiver signals ds - cdma, which is characterized by the fact that consists of the pru00f3bkuju0105cego (up) combined with the generator taktuju0105cym (gt), which is connected with a generator sequence ro zpraszaju0105cej (gsr),which is connected with the first block korelatoru00f3w (k1) consisting of three korelatoru00f3w and first decision-making system (ud1). each korelator built with system mnou017cu0105cego (um) and the cau0142kuju0105cego (uc).the first system decision-making (ud1) is connected with a generator sequence diffuse (gsr), which consists of block control timing (kt), which is connected in series with the signal generator pseudoprzypadkowego (gsp), with a przedmodulacyjnym (fpm) and block przepru00f3bkowania (p).timing control block (kt) is connected directly to the generator taktuju0105cym (gt), and the first system decision-making (ud1).przepru00f3bkowania block (p) is connected with the previous system mnou017cu0105cym (um) and later the mnou017cu0105cym (um) through a block delay (because) signal of one sampling period, with the block korelatoru00f3w (k1) and a filter (fuo) and the switch (uu0142amkowoopu00f3u017aniaju0105cych mux) which is connected, a second korelatoru00f3w (k2)consisting of three korelatoru00f3w and other decision-making system (ud2). each korelator is built with the mnou017cu0105cego (um) and the cau0142kuju0105cego (uc), and the second decision-making system (ud2) is connected with the switch (mux).
