Mobile Unit Communication System

摘要: A mobile unit communication system comprises: units; a TDMA base station for transmitting and receiving signal having first frame to/from units within service area thereof in TDMA/TDD manner; CDMA adjacent to the station, second CDMA/TDD manner, at least one of these stations synchronizing circuit detecting phase between frames according detected phase. Each has communicating with mode; mode. First have same length are synchronized eliminate necessity operation when moves other area. unique word attached framed data is commonly defined signals, so that detection can be used commonly. The signals frequency band, antenna portion amount per channel frame, modulation demodulation circuits
