SUBSCRIBER'S POINT IN SYSTEM OF WIRELESS DIGITAL TELEPHONE COMMUNICATION Russian patent published in 2000 - IPC

FIELD: telephone communication. SUBSTANCE: invention is related to subscriber's point in system of wireless digital telephone communication which includes codec and processing unit for recoding of input signal to generate digital input symbols coupled to codec, radio installation to transmit signal that carries information presented in digital input symbols to second point in system and to demodulate output signal received from this second point. Processing unit synthesizes digital output signals from demodulated output signal and has chip with filter with final pulse characteristic that acts on processing unit which generates filtered digital input symbols with final pulse characteristic for transmission by radio installation. It includes module to decode internal addresses allowing processing unit to select internal functions of filter with final pulse characteristic, control and state registers which enable processing unit to read out state by internal functions of chip with filter with final pulse characteristic, transmission filter with final pulse characteristic intended to filter digital input symbols, reception timing module and transmission timing module providing processing chip with capability to control filter with final pulse characteristic. EFFECT: simplified design of subscriber's point. 8 cl, 5 dwg
