Description
Technical field
The utility model relates to a kind of TD-LTE family access device of supporting double antenna.
Background technology
LTE is based on OFDMA technology, the universal standard organized to set up by 3GPP, comprises that two kinds of patterns of FDD and TDD are for frequency spectrum and non-paired frequency spectrum in pairs.
LTE-TDD, the domestic TD-LTE that also claims, be Time Division Long Term Evolution(time-division Long Term Evolution), each large enterprises of the whole world and the operator by 3GPP tissue, contained formulate jointly, two patterns of FDD in LTE standard and TDD are in fact identical, between two patterns, only have less difference, similarity reaches 90%.[1] TDD is time division duplex (Time Division Duplexing), is one of duplex technology of mobile communication technology use, corresponding with FDD Frequency Division Duplexing (FDD).In fact it doesn't matter for TD-LTE and TD-SCDMA, and TD-LTE is the technology of the LTE of TDD version, and the technology of FDD-LTE is the LTE technology of FDD version.TD-SCDMA is CDMA(code division multiple access) technology, TD-LTE is OFDM(OFDM) technology.Both from encoding and decoding, frame format, eat dishes without rice or wine, signaling, to the network architecture, all different.
In the prior art, the TD-LTE access device of family expenses is only supported an antenna access, and unstable properties, has a strong impact on user's normal use.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of TD-LTE family access device of supporting double antenna is provided, can support two antenna reception TD-LTE signals, increasing device applicable surface, a plurality of filters are set, improve signal stabilization and accuracy, guarantee to receive the integrality of signal.
The purpose of this utility model is achieved through the following technical solutions: a kind of TD-LTE family access device of supporting double antenna, it comprises mixer and terminal box, TD-LTE input signal is connected with the input of mixer, the output of mixer is connected with terminal box, terminal box output TD-LTE output signal.
