Description of the invention: [Technical field to which the invention pertains] In particular, the invention relates to an adjustable impedance. The invention relates to the application of a wireless communication matching circuit. [Prior Art] In the transmission line of high-frequency signals, there are a large number of transmission efficiencies in the transmission lines at both ends of the line, and a high-frequency data transmission path in the transmission of the polling module... This uses impedance matching in the conventional wireless communication. Circuitry to improve energy transfer efficiency. However, as wireless applications are widely switched to many different frequency bands. In addition to this: the communication device may need to be in the communication device, the transmission of the wireless communication application in the portable position and the surrounding objects. The signal processing method that can adapt to different environmental conditions is not yet developed as the device itself cannot meet the above-mentioned various impedance matching circuits that are not called _=solids. SUMMARY OF THE INVENTION One embodiment of the present invention is a communication device including a receiver, a baseband module, a transmitter, a controller, and at least one sensor. The receiver can receive the in-line RF signal to generate an incoming data signal, wherein the receiver includes a plurality of adjustable impedance matching circuits to optimize the conversion of the signal energy. The baseband module can receive the incoming data signal and generate an outgoing data signal. The transmitter can adjust the outgoing data signal to externally transmit an outgoing RF signal. The transmitter includes a plurality of adjustable impedance matching circuits for optimizing the conversion of the signal month bl. The sensor can sense an environmental parameter. The controller root 4 HTC098086-0/〇746-A42049TWf/fmal 201044800 generates at least one control signal according to the environmental parameter for changing the impedance values of the plurality of adjustable impedance matching circuits in the receiver and the transmitter. Another embodiment of the present invention is a signal processing method implemented in the above communication device. First, a plurality of adjustable impedance matching circuits are used to optimize the conversion of signal energy on the signal receiving path, thereby receiving an internal RF signal to generate an internal data signal. A plurality of adjustable impedance matching circuits are then used to optimize the conversion of the signal energy on a signal transmission path, thereby modulating an outgoing data signal to transmit an outgoing RF signal. Finally, at least one environmental parameter is sensed, and at least one control signal is generated according to the environmental parameter, thereby changing the impedance value of the adjustable impedance matching circuits. [Embodiment] FIG. 1 is a structural diagram of a communication device according to an embodiment of the present invention, and the impedance matching circuits used in the prior art are all changed to an adjustable impedance matching circuit. One or more sensors 1〇4 are used in the communication device 100 to sense various environmental parameters as a basis for adjusting these adjustable impedance matching circuits. In the communication device 100, a receiver 11A, a baseband analog group 130 and a transmitter 120 are mainly included. The receiver 11 is operable to receive an incoming RF signal to generate an incoming data signal #SIN. The baseband module 13 is coupled to the receiver 110 to receive the incoming data signal and generate an outgoing data signal #s0UT. The transmitter 120 can adjust the outgoing data signal #8 to listen to the external transmission and send an external RF signal. Different from the conventional technology, the receiver and transmitter 120 include a plurality of adjustable impedance matching circuits that can be flexibly adjusted with changes in environmental parameters to optimize signal energy conversion. The communication device 100 includes a controller 14A coupled to the sensor 1〇4, and generates at least one control signal according to the environmental parameter for changing the receiving HTC098086-0/0746-A42049TW bit final 5 201044800 state 110 And an impedance value of the adjustable impedance matching circuit in the transmitter 120. The traditional baseband module processes the fundamental frequency signal, so there is no design of a tunable impedance matching circuit. However, in the embodiment of the present invention, the baseband module 130 may be a software defined radio (s〇ftwareradi〇) module. The inbound data signal #SlN and the outgoing data signal #s〇ut define a radio signal for the software, that is, the baseband module 13 can directly process the high frequency digital signal without going through the up-conversion modulation. Stage. Also, since the processed signal belongs to the field of frequency, the configuration of the adjustable impedance matching circuit is also required between the baseband module 13A and the receiver 11A and the transmitter 120. As shown in FIG. 1 , an adjustable impedance matching circuit 2〇〇c′ is disposed between the receiver 110 and the baseband module 13〇, and an adjustable type is disposed between the baseband module 13〇 and the transmitter 12〇. The impedance matching circuit 2〇〇d. Similarly, the adjustable impedance matching circuits 200c and 200d can be flexibly adapted to changes in environmental parameters by the control of the controller 140. For example, the controller 140 adjusts the impedance value of the adjustable impedance matching circuit 200c according to the environmental parameter to optimize the energy transmission efficiency of the transmitted data signal #sw. On the other hand, the controller 14 adjusts the impedance value of the adjustable impedance matching circuit 2〇〇d according to the environmental parameter, thereby optimizing the energy transmission efficiency of the external feed signal #SOUT. However, the present invention does not limit the baseband module 130 to a software-defined radio module. If the baseband module 130 is a conventional conventional baseband module, the adjustable impedance matching circuits 200c and 200d in the second diagram are not essential components and can be removed. In the receiver 110, a receiving antenna 112, a filter 114 and a demodulation transformer Π6 are roughly included. Receiving antenna 112 can receive in-line RF signal HTC098086-0/0746-A42049TWMnal 6 201044800

On the other hand, a transmitter antenna 122, a power amplifier 124, and a mixer 126 are roughly included in the transmitter 12A. The mixer 126 is coupled to the baseband module 130, and can adjust the outgoing data signal #8〇町 to generate an outgoing RF signal, and the power amplifier 124 is coupled to the mixer 126 to amplify the external transmission.

Wherein, an adjustable impedance matching circuit 2〇〇e is located between the power amplifier 124 and the mixer 126 and is controlled by the control voltage #Ve. A tunable impedance matching circuit 200f is located between the transmit antenna 122 and the power amplifier 124 and is controlled by the control voltage.

The sensor 104 can be applied to the sensor ΠΗ can be ~ distance pan. For example, 100 is close to an object. The sputum is used to sense the communication device. For the hand-held mobile device, the 'speaking brother' is the distance from the object.

More-step 5 * Near H' field shape Folded state and open state are two kinds of ^, for example, a folding type mobile phone, which has two distinct fields. For the slider ^ mobile phone, the overlap state and the slide open state are also two different field shapes, each of which requires the same impedance (9) parameter. Therefore, the dynamic adjustment of the adjustable impedance matching circuit (4) should be such that h is (4) improved quality. The controller 14G includes a lookup table 142 for defining the environment parameter and the control call. As for the details of the environmental parameter values, it is not limited to the present invention. & These values can be used to find better results by experiment or experience, and are defined in the lookup table 142 in advance. When the controller (10) receives the environmental parameter, it can directly check the thief check wire I42 to generate the control signal. The general impedance matching circuit is composed of a capacitor and a sense of f. The adjustable impedance matching circuit in the embodiment of the present invention uses a voltage-controlled capacitor, which can be controlled by voltage to change the capacitance value, thereby changing the entire impedance. The control signal generated by the controller after querying the lookup table 142 may be a voltage signal, and the value of the control capacitor in the adjustable impedance matching circuit is directly applied to adjust the impedance of the adjustable impedance matching circuits. Due to the impedance matching circuit HTC098086-0/0746-A42049TWf7fmal. The structure and connection of the 201044800 differs depending on the application and component structure of the communication device. The present invention is not limited to the specific embodiment, and mainly emphasizes the concept of the voltage control system to the controller. Figure 2 is a flow chart of the signal processing method of the present invention. The signal processing method is mainly implemented in the communication device as shown in Fig. i. In step 201, the communication device (10) is activated, and the receiver m forms a signal receiving path: after the transmitter 120 forms a signal transmitting path, the two-way components passing between them adopt the adjustable method proposed by the present invention. The impedance matching circuit is connected in series. At step 203, at least - the sensor 1 〇 4_ environmental parameters. In step 205, the controller 14 queries a query table 142 to generate control voltages corresponding to the respective adjustable impedance matching circuits according to the environmental parameters, such as control voltage #%, #¥13, #%, _,# %, #^, etc. In step 207, the controller 14 transmits the control voltages to corresponding adjustable impedance matching circuits, such as the adjustable impedance matching circuits 2〇, 2嶋, 200c, 200d, 200e, 200f. The voltage-controlled capacitor is affected to change the impedance matching effect. The controller 140 described in the present invention is not limited to one, and may be a plurality of simultaneous negative sensing different items. The items that are responsible for sensing are not limited to only object distances. For example, a handheld mobile device with its front side facing up or down has a slight impact on wireless transmission and can therefore be listed as one of the sensing items. Some mobile phone antennas are retractable, so the telescopic status of the antenna can also be included in one of the sensing items. On the other hand, the communication band between the mobile phone and the base station may have many different values, which is one of the factors for adjusting the adjustable impedance matching circuit. The lookup table 142 can establish a cross-reference table between the sensed plurality of environmental parameters and the control voltage, so that the control HTC098086-0/0746-A42049TWf7fmal 〇201044800 140 can be quickly found under various combinations of conditions. Control Voltage Value 0 Although the invention has been described above by way of a preferred embodiment, it is to be understood that the scope of the invention is not necessarily limited. Rather, any modifications based on the same spirit or the ordinary skill in the art to which the invention pertains are obvious.
