一方、 電波法においては、 2. 4 GHz帯における 1波あたりの周波数占有帯 域幅は、 26 MHz以下と標準規格 (AR I B： Association of Radio Industries and Businesses STD-T66) により定められており、 力つデジタル通信方 式を用いて送受信を行うことが規定されている。 現在、 ステレオ音声及ひ mi象等 のアナログ信号を無線回線で伝送する手法は、 スぺクトル拡散通信方式を用い、 力 通信路は周波数分割により通信することが広く実用に供されている。  On the other hand, according to the Radio Law, the frequency occupied bandwidth per wave in the 2.4 GHz band is set to 26 MHz or less according to the standard (AR IB: Association of Radio Industries and Businesses STD-T66). It is specified that transmission and reception are performed using power digital communication method.

Becomes indispensable, and the electronic circuit system including the modulation / demodulation circuit is complicated and leads to an increase in cost.
無線通信路の確保においては周波数分割方式が多く、 その結果、 秘匿性に乏し く、 更に電波法の規制から広帯域幅による多チャンネル化が困難である。  There are many frequency division schemes for securing wireless communication channels. As a result, confidentiality is poor, and it is difficult to increase the number of channels over a wide bandwidth due to the regulations of the Radio Law.
従って、 本発明は、 複雑な圧縮、 伸長技術を必要とせず、 カゝっ省電力で周波数 占有帯域幅も電波法に準拠し、 更に電子回路系がシンプルで、 デジタルデータ、 音声、 高画質 等の情報を、 秘匿性の優れた多チャンネルの通信路で伝送でき る無線情報通信装置及び方法を «することを目的としている。 発明の開示  Therefore, the present invention does not require complicated compression and decompression techniques, saves power, is compliant with the Radio Law, and has a simple electronic circuit system, digital data, voice, high image quality, etc. It is an object of the present invention to provide a wireless information communication device and method capable of transmitting such information through a multi-channel communication channel with excellent secrecy.

The audio signal is a stereo signal. Two audio signals are separately input to the stereo modulator 11, and the stereo modulator 11 outputs a stereo composite signal. ! The elephant signal is input to the video amplifier 12 and amplified. The stereo composite signal (audio signal) from the stereo modulator 11 as an analog signal is modulated in accordance with the PM (Phase Modulation) method by the audio analog modulator 13 and the analog output is output from the elephant amplifier 12.

When an ASK, FSK, or BPSK (Binary Phase Shift Keying) modulator is used instead of the QPSK modulator 17, multiplexing processing for audio, video, and channel code signals is required. A modulated signal of information output from the QPSK modulator 17 is converted into a frequency in a quasi-microwave band by the frequency converter 20 and further amplified to a predetermined power level by the high-frequency power amplifier 21.

When used, the frequency occupied band is 1/2 that of the BPSK modulator.
更に、 メモリ回路 2 5を利用する C P U 2 4によって、 例えば、 音声及び S¾象 の再現に利用されるチヤンネル識別符号を制御することにより、 音声信号及び映 像信号の制御が可能となり、 実質的に音声信号だけ、 あるいは、 ^(象信号のある フレーム （静止画） だけを有効な情報として■することも可能となる。 この場 合、 実質的な符号分割多重通信がなされることとなる。  Further, the CPU 24 using the memory circuit 25 can control the audio signal and the video signal, for example, by controlling the channel identification code used for reproducing the audio and the S image.

一方、 Q P S K復調器 5 6力ら Q信号として出力されるチヤンネル識別符号は、 チヤンネル リ符号変 « 7 3により、 例えば、 †生ィンピーダンスが 5 0ォー ムとなるデジタル信号に変換され、そのデジタル信号が第一の二重変調器 (DBM) 7 4の I Fポートに入力する。 第一の二重変調器 7 4の L Oポートには、 搬送波 発生器 6 5からの、 例えば、 2 0 0 MH zの搬送波が入力され、 その R Fポート 力ら二相位相変調 (B P S K) の信号 （週言用チャンネル IJ信号） が出力され る。その二相位相変調の信号が S AWコンポルバ 7 5の一方の入力端に入力する。 第二の二重変調器 (DBM) 7 6の L Oポートには搬送波発生器 5 6から分配され た 2 0 0 MH zの搬送波が入力され、 その I Fポートには受信用チヤンネル識別 符号発生器 6 6カゝらのチヤンネル 符号が入力され、 その R Fポートから受信 用参照 BP SK変調信号 （受信用チャンネル l sリ信号） が出力される。 その受信 用参照 BPS K変調信号は、 S AWコンボルバ 75の他方の入力端に入力する。 SAWコンボルバ 75の出力端からは、 送受信のチャンネル識別符号が一致した 時点で相関信号が出力され、 その相関信号が高周波増幅器 67で増幅された後に エンベロープ検波器 68によって検波される。 検波信号は、 基準同期クロック発 生器 58からの基準クロックに同期して動作する AZD変 69にてデジタル 信号に変換され、 受信用分離同期回路 59に入力する。 受信用分離同期回路 59 は、 入力される前記検波信号 （送受信のチャネル翻リ符号が一致したタイミング を表すデジタル信号） を音声及ぴ映像のビット同期信号或レ、はフレーム同期信号 として利用する。 その結果、 ビット同期信号及びフレーム同期信号の発生がなか つた 、 音声信号及び映像信号の再生が困難となり、 秘話、 秘匿性が確保でき る。 On the other hand, the channel identification code output as a Q signal from the QPSK demodulator 56 is converted into a digital signal having a generated impedance of 50 ohms, for example, by the channel recode conversion 733. A digital signal enters the IF port of the first double modulator (DBM) 74. The LO port of the first duplex modulator 74 receives, for example, a carrier of 200 MHz from the carrier generator 65, and the RF port outputs a two-phase phase modulated (BPSK) signal. (Weekly channel IJ signal) is output. The signal of the two-phase modulation is input to one input terminal of the SAW compolator 75. The carrier of 200 MHz distributed from the carrier generator 56 is input to the LO port of the second double modulator (DBM) 76, and the reception channel identification code generator 6 is input to the IF port thereof. 6-channel code is input and received from its RF port BP SK modulation signal (receive channel ls signal) is output. The receiving reference BPSK modulation signal is input to the other input terminal of the SAW convolver 75. A correlation signal is output from the output terminal of the SAW convolver 75 when the transmission and reception channel identification codes match, and the correlation signal is amplified by the high frequency amplifier 67 and then detected by the envelope detector 68. The detection signal is converted into a digital signal by the AZD transformer 69 operating in synchronization with the reference clock from the reference synchronization clock generator 58 and input to the reception separation synchronization circuit 59. The receiving / separating synchronization circuit 59 uses the input detection signal (a digital signal indicating the timing at which the transmission / reception channel reversal codes match) as a bit synchronization signal or a frame synchronization signal for audio and video. As a result, while the bit synchronization signal and the frame synchronization signal are not generated, it is difficult to reproduce the audio signal and the video signal, and confidentiality and confidentiality can be secured.

(Still image) alone can be played.
