Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 3, time division multiplexing antenna system of the present invention, by baseband processing circuitry, data transmit-receive circuit, data owner antenna, duplexer, voice transmitting-receiving circuit, multiplex antenna is formed; Data transmit-receive circuit and voice transmitting-receiving circuit establish a communications link with baseband processing circuitry respectively, and data transmit-receive circuit main road is connected with the data owner antenna, and the secondary road of data transmit-receive circuit is connected with multiplex antenna through duplexer; The voice transmitting-receiving circuit connects through duplexer and multiplex antenna; Duplexer also establishes a communications link with baseband processing circuitry.The secondary road of said data transmit-receive circuit is the secondary road diversity reception circuit of data.
Among the present invention; The secondary road diversity reception circuit of data and the multiplexing same antenna of voice receiving circuit, terminal voice transmitting-receiving circuit are when standby is idle, and this multiplex antenna is that the secondary road diversity reception circuit of data uses; The terminal is when conversing or intercepting network, and this multiplex antenna is that the voice transmitting-receiving circuit uses.Multiplex antenna is passed through baseband processing circuitry control antenna switch transition, time division multiplexing between secondary road diversity reception circuit of data and voice transmitting-receiving circuit.Said duplexer is single-pole double-throw switch (SPDT) or the switch with identical function.The electric wire switch turns to the voice transmitting-receiving circuit logic identical in the logic of opening the voice transmitting-receiving circuit with baseband circuit; When baseband signal when speech business or terminal standby are intercepted network; Open the voice transmitting-receiving circuit; Open described duplexer to voice transmitting-receiving circuit one end simultaneously, this multiplex antenna is used for the voice transmitting-receiving circuit, and described multiplex antenna of all the other times is that data diversity receives use.
The data service of mobile communication terminal according to the invention and speech business can be the one-segment single systems, also can be the multiband multi-modulation schemes.Introduce the triband data service below and how the triband speech business realizes the time division multiplexing antenna, specific as follows.
