Case (TD-SCDMA), the characteristics such as tdd mode and smart antenna new technology are greatly prized by and at three main candidate standards
One of.Fdd mode rules all the land in the first generation and second generation mobile communication system, and tdd mode does not draw attention.But due to
Many advantages of the needs of new business and the development of new technology and tdd mode, tdd mode will be paid more and more attention.
The working principle of time division duplex is as follows: TDD is a kind of duplex mode of communication system, is used in mobile communication system
It is received and transmission channel (or uplink downlink) in separation.It is received in the mobile communication system of tdd mode and transmission is same
Frequency channels, that is, carrier wave different time-gap separates reception and transmission channel with the time is guaranteed；And the mobile communication system of fdd mode
The reception and transmission of system are that reception and transmission channel are separated with frequency range is guaranteed on two symmetrical frequency channels of separation.
It is different using the mobile communication system feature of different dual-modes with benefit is communicated.The movement of tdd mode is logical
The same frequency of uplink and downlink channel in letter system, thus the reciprocity with uplink and downlink channel, this is logical to the movement of tdd mode
Letter system brings many advantages.
In tdd mode, the transmission of information can carry out in same carrier frequency in uplink and downlink, i.e.,
The transmission of information is to be realized on same carrier wave by the time-division in the transmission of information and downlink in uplink.
