Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit 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 main antenna, duplexer, voice transmitting-receiving circuit, multiplex antenna forms; 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 data main antenna, and the secondary road of data transmit-receive circuit is connected with multiplex antenna through duplexer; Voice transmitting-receiving circuit connects through duplexer and multiplex antenna; Duplexer also establishes a communications link with baseband processing circuitry.The secondary road of described data transmit-receive circuit is the secondary road diversity reception circuit of data.
In the present invention, the secondary road diversity reception circuit of data and the phonetic incepting circuit multiplexer same antenna, terminal speech transmission circuit is when the standby free time, and this multiplex antenna is that the secondary road diversity reception circuit of data uses, terminal is in call or when intercepting network, and this multiplex antenna is that voice transmitting-receiving circuit uses.Multiplex antenna passes through baseband processing circuitry control antenna switch transition, time division multiplexing between the secondary road diversity reception circuit of data and voice transmitting-receiving circuit.Described duplexer is single-pole double-throw switch (SPDT) or the switch with identical function.Electric wire switch turns to voice transmitting-receiving circuit logic identical with the logic that baseband circuit is opening voice transmitting-receiving circuit, when baseband signal intercepts network in speech business or terminal standby, open voice transmitting-receiving circuit, open described duplexer to voice transmitting-receiving circuit on one side simultaneously, this multiplex antenna is that voice transmitting-receiving circuit uses, and the multiplex antenna described in all the other times is that data diversity receives use.
The data service of mobile communication terminal of the present invention and speech business can be one-segment single systems, also can be multiband multi-modulation schemes.Introduce three wave band data business below and how three wave band speech businesses realize time division multiplexing antenna, specific as follows.
