In this example, a communication terminal, for example, a mobile phone, will be used as an example of an electronic device to which a wireless communication function is added.

As shown in FIG. 1, the radio receiver 1 includes a radio signal receiver 4 for receiving radio signals through the antenna 2 and the antenna switch 3, a radio signal feature extractor 5, and a radio receiver. It is comprised including the signal converter 6.

The radio signal feature extraction unit 5 extracts a feature from the frequency, modulation, or the like of the received radio signal, and identifies a communication scheme from the extracted feature. The radio signal feature extraction section 5 of the present embodiment identifies whether the communication scheme A or communication scheme B is from the extracted features. Then, the identified result is transmitted as the control signal S to the radio signal converter 6 or the modem / baseband received signal processor 7.

The radio signal converter 6 down-converts, for example, a received radio signal, i.e., a high frequency radio signal including a carrier frequency, into a lower low frequency received signal and transfers it to the modem / baseband received signal processor 7. The wireless signal converter 6 of the present embodiment takes either a down converting method corresponding to the communication method A or a down converting method corresponding to a communication method B different from the communication method A based on the control signal S at the time of down converting. do.

And a demodulation section 9B, a communication sequence processing section 10B, a decoding section 11B, and a reception data output switch 12 corresponding thereto.

The received signal input switch 8 transmits the received signal output from the radio signal converter 6 to either the demodulator 9A or the demodulator 9B based on the control signal S. FIG.

Here, when it is identified in the radio signal feature extraction section 5 that the communication mode of the received radio signal is "A", the reception signal input switch 8 transmits the reception signal to the demodulation section 9A. The demodulator 9A demodulates the received signal transmitted using the demodulation method corresponding to the communication method A. FIG. The demodulated received signal is transmitted to the communication sequence processor 10A. The communication order processing unit 10A uses a communication order processing method corresponding to the communication method A, and performs communication order processing on the demodulated received signal. The communication sequence processing here refers to, for example, a process of separating voice data, control data, and the like from the demodulated received signal. The received communication signal processed in communication order is transferred to the decoding unit 11A. The decoding unit 11A decodes the received signal processed using the decoding method corresponding to the communication method A, and outputs it as received data.

In addition, when it is identified in the radio signal feature extraction section 5 that the communication mode of the received radio signal is " B ", the reception signal input switch 8 transmits the reception signal to the demodulation section 9B. Thereafter, the demodulation section 9B demodulates the received signal using the demodulation scheme corresponding to the communication system B, and the communication sequence processor 10B demodulates the received signal corresponding to the communication system B. Communication order processing is performed using the processing method, and the decoding unit 11B decodes the received signal processed in the communication order using the decoding method corresponding to the communication method B, and outputs it as received data.

The reception data output switch 12 directly communicates the reception data (voice data in this embodiment) output from the decoding unit 11A or the decoding unit 11B based on the control signal S, or includes a D / A converter or the like. It transfers to the speaker 13 through a part (not shown).

The modem / baseband transmission signal processing section 14 includes a transmission data input switch 15, an encoding section 16A corresponding to communication scheme A, a communication sequence processor 17A, a modulator 18A, and communication scheme B, respectively. A coding unit 16B, a communication sequence processor 17B, a modulator 18B, and a transmission signal output switch 19 are configured.

The transmission data input switch 15 encodes transmission data (voice data in this example) input directly from the microphone 20 or through a communication unit (not shown) including an A / D converter or the like based on the control signal S. It transfers to either the part 16A or the encoding part 16B.

Here, when it is identified that the communication method of the radio signal received by the radio signal feature extraction unit 5 is "A", the transmission data input switch 15 transmits the transmission data to the encoding unit 16A. The encoder 16A encodes the transmitted data transmitted using an encoding scheme corresponding to the communication scheme A. FIG. The encoded transmission data is transferred to the communication sequence processor 17A. The communication order processing unit 17A performs communication order processing on the transmission data encoded using the communication order processing method corresponding to the communication method A. FIG. The communication sequence processing here refers to a process of multiplexing encoded transmission data and control data, for example. The transmission data processed in the communication order is transferred to the modulator 18A. The modulator 18A modulates the transmission ordered transmission signal using the modulation method corresponding to the communication method A, and outputs it as a transmission signal.

In addition, when it is identified that the communication method of the radio signal received by the radio signal feature extraction unit 5 is "B", the transmission data input switch 15 transmits the transmission data to the encoding unit 16B. Thereafter, the transmission data transferred by the encoding unit 16B is demodulated using the encoding method corresponding to the communication method B, and the transmission data encoded by the communication sequence processor 17B is the communication sequence corresponding to the communication method B. Communication order processing is performed using the processing method, and the modulating unit 18B decodes the transmission data processed in the communication order using a modulation method corresponding to the communication method B, and outputs the data as a transmission signal.

The transmission signal output switch 19 transfers the transmission signal output from the modulator 18A or the modulator 18B to the radio transmitter 21 based on the control signal S. FIG.

The radio transmitter 21 includes a radio signal converter 22 and a radio signal transmitter 23 for transmitting a transmission signal as a radio signal through the antenna switch 3 and the antenna 2.

The radio signal converter 22 up-converts, for example, the frequency of the transmitted transmission signal (low frequency) to a radio carrier frequency of a higher frequency, and transmits it to the radio signal transmitter 23. At the time of up-converting, the radio signal converter 22 of the present embodiment takes either an up-converting method corresponding to the communication method A or an up-converting method corresponding to the communication method B based on the control signal S.

The radio signal transmitter 23 amplifies the up-converted transmission signal to the transmission power level, and then transmits the transmission signal as a radio signal through the antenna switch 3 and the antenna 2.

In the case of a communication terminal having such a wireless communication system, the feature of the radio signal is extracted from the received radio signal and the communication scheme is identified from the extracted feature. And based on this identification result, the conversion method of the wireless signal conversion part 6, the demodulation method of the modem / baseband reception signal processing part 7, the communication sequence processing method, the decoding method, the modem / baseband transmission signal processing part 14 ), A coding method, a communication order processing method, a modulation method, and a conversion method of the wireless signal conversion unit 22 are respectively switched to a method corresponding to the identified communication method. Accordingly, one communication terminal can cope with a plurality of communication methods.

In addition, since the communication method is identified from the characteristics of the extracted wireless signal and the communication method is switched based on the identification result, troublesome operation, for example, a switching operation of the operator, can be eliminated.

In addition, a feature is extracted from the received wireless signal and a communication scheme is identified from the extracted feature. That is, since the communication method is identified at the step of receiving the radio signal, it is possible to promote commonization of circuits for receiving and receiving the received radio signal, for example, frequency conversion circuits, modulation and demodulation circuits, communication sequence processing circuits, and code decoding circuits. It can also be effective. As described above, in the present invention, since the commonization of circuits can be promoted, it is also advantageous in miniaturization of communication terminals and cost reduction.

In the first embodiment of the present invention, the conversion schemes of the radio signal converters 6 and 22 are switched in accordance with the communication schemes A and B, but this is not necessary. This is because, for example, when the carrier frequency of the communication method A and the carrier frequency of the communication method B are the same, the down conversion of the radio signal conversion unit 6 and the up conversion of the radio signal conversion unit 22 are possible. .

In addition, in the first embodiment, both the receiving side and the transmitting side are configured to be compatible with the respective communication methods A and B. FIG. The effect of this configuration is that bidirectional communication is possible even when the communication terminal of the other party or the base station relaying the radio signal can only cope with one communication method.

However, this invention should just be comprised so that at least only the receiving side can respond to each of communication systems A and B. For example, when a communication terminal of a counterpart or a base station for relaying a radio signal is provided with the radio communication system according to the present invention, even if the communication method of the transmitted radio signal is any method, bidirectional communication is possible.

The transmission data input line 26 is connected to each of the coding units 16A and 16B.

In addition, the transmission data input directly from the microphone 20 or through a communication unit (not shown) including an A / D converter or the like is transmitted to the transmission data input line 26 of the modem / baseband transmission signal processing unit 14. Is passed to.

As a result, the transmission data transmitted to the transmission data input line 26 is input to the encoding section 16A, and subsequently input to the communication sequence processing section 17A and the modulation section 18A. The transmission signal output from the modulator 18A is transmitted to the wireless signal converter 22 through the transmission signal output line 27.

In addition, when it is identified in the radio signal feature extraction section 5 that the communication method of the received radio signal is "B", the encoding section 16B, the communication sequence processing section 17B, and the modulation section are based on the control signal S. 18B are activated, respectively, and the coding unit 16A, the communication sequence processing unit 17A, and the modulation unit 18A are deactivated, respectively. Therefore, the transmission data transmitted to the transmission data input line 26 is input to the encoder 16B, and subsequently to the communication sequence processor 17B and the modulator 18B. The transmission signal output from the modulator 18B is transmitted to the wireless signal converter 22 through the transmission signal output line 27.
