Claim Text:
1. A mobile terminal, comprising: an antenna, a wireless communication transmitting module and a mobile multimedia broadcast receiving module which are connected with the antenna, a first filter which is connected between the wireless communication transmitting module and the antenna, and a second filter which is connected between the mobile multimedia broadcast receiving module and the antenna, wherein: the first filter and the second filter are configured to suppress sideband noise generated on the mobile multimedia broadcast receiving module when the wireless communication transmitting module transmits signals; the wireless communication transmitting module comprises a first wireless communication transmitting module and a second wireless communication transmitting module, the first wireless communication transmitting module is a Global System for Mobile, GSM, 900 wireless communication transmitting module, the second wireless communication transmitting module is a Personal Communications Services, PCS, 1900 wireless communication transmitting module; the mobile multimedia broadcast receiving module comprises a first mobile multimedia broadcast receiving module and a second mobile multimedia broadcast receiving module, the first mobile multimedia broadcast receiving module is a China mobile Multimedia Broadcasting, CMMB, U-band receiving module, the second mobile multimedia broadcast receiving module is a CMMB S-band receiving module; the first filter is configured to allow signals in GSM900 transmitting frequency bands of the GSM 900 wireless communication transmitting module and PCS1900 transmitting frequency bands of the PCS1900 wireless communication transmitting module pass through successfully, but attenuate sideband noise in U-band of the CMMB U-band receiving module and S-band of the CMMB S-band receiving module; the second filter is configured to suppress sideband signals in the GSM900 transmitting frequency bands of the GSM 900 wireless communication transmitting module and PCS1900 transmitting frequency bands of the PCS1900 wireless communication transmitting module, but do not attenuate CMMB signals of the CMMB U-band receiving module and the CMMB S-band receiving module at all; and interference brought by the GSM900 sideband does not bring interference with the CMMB in the U band, and interference brought by the PCS1900 sideband does not cause interference with the CMMB in the S band.
