ACQUISITION ADJUSTMENT SYSTEM USING CODED RULE VIOLATION CODE

摘要

PURPOSE:To attain ACQ adjustment without decreasing the data transmission capacity for the acquisition(ACQ) by sending a coded violation code from a subscriber station to a base station as a data for the ACQ, decoding its rule violation code at the base station and recognizing the position of the violation code of the subscriber station. CONSTITUTION:A code rule violation code CRV subject to CMI(Code Mark Inversion) coding sent from a subscriber station 1 through a transmission line 100A is decoded by a CRV(code rule violation code) decoder 21 and its decoded output is inputted to a data generating section 22. A CRV position recognition device 221 recognizes a distance between a base station and the subscriber station 1 from the CMI composite output of the CRV decoder 21, an ACQ calculator 222 calculates the delay time value to be adjusted by the subscriber station 1 and the resulting ACQ data is fed to a transmission line 100B. A data processing unit 121 of the subscriber station 1 extracts the ACQ data sent through the transmission line 100B from the output of a radio receiver 1R to apply data processing and a display device 122 displays the delay time to be connected for acquisition adjustment by its own station 1.
