Embodiment
The embodiment of the present invention provides a kind of processing method of signal, can improve the signal quality of native system terminal by the antenna of other system.The embodiment of the present invention also provides corresponding signal processing system.Below be described in detail respectively.
Consult Fig. 1, the first embodiment of signal processing method embodiment of the present invention comprises:
101, the signal that sends of the first antenna receiving terminal, the second antenna receives the identical signal that described terminal sends, and wherein, the frequency of described signal is positioned at described first antenna and the common receive frequency range of the second antenna.
The band limits of the signal that the first antenna receives and the signal that the second antenna receives is exactly the range of receiving of antenna to signal, described first antenna and the second antenna have common receive frequency range, mean that the signal that described first antenna receives has overlapping with the signal that the second antenna receives.
Suppose that TD antenna can receive the signal of 1770MHz ~ 2170MHz, GSM antenna can receive the signal of 1880MHz ~ 2250MHz, the overlapped frequency bands of the signal that TD antenna receives and the signal that GSM antenna receives is 1880MHz ~ 2170MHz, this situation regards the signal cross overlap that the signal that the first antenna receives and the second antenna receive as, if GSM antenna is dual-mode antenna, the band limits of the signal wherein having an antenna opening to receive is 1880MHz ~ 1920MHz, this situation also regards that the signal that the second antenna receives has overlapping with the signal that the first antenna receives as, as, the band limits of the signal that terminal sends is 1880MHz ~ 1881.6MHz, no matter which kind of situation, working frequency points 1880MHz ~ the 1881.6MHz of terminal drops in overlapping region, TD system is used and gsm system is illustrated in the present embodiment, but the invention is not restricted to TD system and gsm system, antenna between other system also can utilize mutually, as: the mutual utilization between TD-SCDMA system and WCDMA antenna, long evolving system (LTE, LongTermEvolution) the mutual utilization and between TD-SCDMA antenna, mutual utilization between WCDMA system and GSM antenna, or the mutual utilization between above-mentioned each system and other standard antennas, as long as the antenna be utilized and native system have frequency range to partly overlap.Such as, A system, utilize B system antenna, and so the antenna of B system at least can receive the part signal of A system.No matter be the antenna which kind of system utilizes other system, above-mentionedly utilize process, utilize the process of GSM antenna similar with TD-SCDMA.
102, the terminal signaling of the first antenna described in radio frequency processing and the reception of the second antenna.
The terminal signaling that first antenna described in radio frequency processing and the second antenna receive refers to the signal of signal overlap and the signal of the first frequency range that receive with the first antenna in the signal that described in radio frequency processing, the second antenna receives;
