METHOD AND TERMINAL FOR ELIMINATING MUTUAL INTERFERENCE BETWEEN TERMINAL MODES

摘要

A method and terminal for eliminating mutual interference between terminal modes, the terminal comprising reception/transmission paths supporting a first mode and a second mode; the transmission path supporting the two modes comprises an antenna switch and a power amplifier (PA); the reception/transmission paths comprise a digital baseband (DBB) chip; the terminal further comprises a high-Q-value filter located between the antenna switch and the PA for filtering the signals to be transmitted in the two modes. The technical solution of the present invention effectively solves the problem of mutual interference in transmissions from dual-mode dual-standby terminals of the time division-synchronous code division multiple access (TD-SCDMA)/global system for mobile communication (GSM).
