MULTIPATH RECEIVER AND MULTIPATH RECEIVING METHOD OF WIRELESS MOBILE COMMUNICATION SYSTEM USING SEQUENTIAL MULTIPATH SIGNAL COMPOSITION

摘要

PURPOSE: A multi-path receiver and a multi-path receiving method of a wireless mobile communication system using a sequential multi-path signal composition are provided to decrease power consumption and make a high speed communication possible by decreasing a memory buffer necessary for a signal composition and a signal align, thereby simplifying a circuit. CONSTITUTION: An RF/IF block(1) separates and passes transmitting/receiving frequencies. An A/D converter(2) converts an analogue signal into a digital signal. A correlator(3) receives the digital signal from the A/D converter(2) and calculates a correlation with a PN code column. An integrator(4) is provided for a signal accumulation during a data sampling period based on a data transmission rate. A memory(9) is used for storing demodulation data as a multi-path difference. A memory controller(10) controls a memory reading/writing for composing the 'n' number of demodulation data being outputted per a data period from each path receiver with previous data stored in the memory(9) in a sequential multi-path. A sequential multi-path signal composition device(11) performs a signal composition and an output of each path receiver(8) being created during each demodulation data period with a signal pre-stored in the memory(9).
