Frame structure for a multi-rate CDMA communication system

摘要

In a CDMA radio transmitting apparatus that controls generation of unnecessary frequency components, variable data (101), after assembled by frame assembly circuit (102) in frame units, is time-multiplexed with fixed data (103) in slot assembly circuit (104). At this time, slot assembly circuit (104) reads the placement location information of fixed data in each slot from memory (203) and carries out time-multiplexing based on the information using random patterns whose repetition cycle is one super frame.
