ABSTRACT:
An apparatus for verifying diversity of a base station in a mobile communication system in which the base station outputs at least one antenna signal using a space-time transmit diversity. Attenuators attenuate and output each antenna signal according to reception sensitivity of a terminal. A coupler couples the signals output from the attenuators with each other and outputs a coupled signal. The terminal receives the coupled signal and demodulates the received signal. A computer is connected to the terminal, and monitors an operation state of the terminal while receiving the signal from the base station, and performs an error check for determining if an error exists in the signal received in the terminal.
