BASE STATION SYSTEM OF FREQUENCY HOPED/CDMA SYSTEM

摘要

PURPOSE: A base station system in an FH/CDMA(Frequency Hopping/Code Division Multiple Access) system is provided to remarkably reduce the weight or size of a coupler in multiplexing and combining RF signals using a digital switch and a BPF(Band Pass Filter) and to minimize the transmitting combination loss of a transmitting signal through junction coupling. CONSTITUTION: Signals processed by 8 signal processing units(201) are inputted to a forward signal exchange unit(202). The processed signals are exchanged through unused channels at the forward signal exchange unit(202) and inputted to another signal processing units(203). The signals processed by the signal processing units(203) are inputted to transmitting/receiving selection units. Signals passed through a path selected by the transmitting/receiving selection units pass a corresponding band through a BPF and are switched at a TDD switch(207) so as to be connected with an antenna. Signals selected by the transmitting/receiving selection units are processed by another signal processing units(204) and exchanged at a backward signal exchange unit(205). The exchanged signals are processed and received through 8 channels identical to a signal processing unit(206).
