It is used when doing.

In the present invention, the "robust wireless transmission method" refers to a frequency band (eg, an unlicensed industrial scientific and medical band, an unlicensed low power frequency band, etc.) and a local characteristic that are not limited to the use of frequency in short-range wireless communication. According to the regulation / regulation of the Radio Law, the weak radio wave of UHF (ultra high frequency) band is selected and the same frequency band (one common channel, e.g. 125MHz of 5.725 ~ 5.850GHz) can be operated simultaneously by several users. Even when shared, the error rate of data transmission in the range of -3 to 10 to -10 power of 10 from the effect of intentional or unintentional multiple access interference of different frequency bands between users or adjacent to each other (BER) Rate can be independently protected from the original signal and the channel assigned by the user with the quality of communication transmission, and the modulated signal has a TDMA RF unit. It is a digital symbol level of binary (1 and 0) bit streams that can be used, and encryption and channel coding that enables digital wireless multiplexing and access. channel coding).

Therefore, in the case of multimedia data, the "robust modulation radio unit" of the present invention should use radio waves of an industrial scientific and medical (ISM) and an unlicensed small output frequency band without restriction on the use of frequency for short-range wireless communication. Simple data using the frequency of band should use weak radio wave of UHF (ultra high frequency) band prescribed by Radio Law according to local characteristics, and depending on the nature of these transmitted data (simple data, audio, video, still image, etc.) Modulation-demodulation method must be used to guarantee transmission error in the range of -3 to -10 of 10. The RF (Radio Frequency) component of the last stage of transmission and the first stage of reception must be used. Low power consumption (less than 100mW) TDMA RF components should be available. In particular, the "Robust Modulation Radio Unit" uses OOK (On / Off Keying) demodulation method for the last stage modulation method and the first stage demodulation method when the weak radio wave of the UHF band is used for simple data transmission (transmission and reception). It must be included.

Minimum BER for simple data <10-8 ~ 10-10

 The channel is configured by using a known (or private) baseband modulation and demodulation method, and then the minimum BER for each generated channel is measured to classify the channel by transmission data type to examine the performance of the channel. The method is, for example, a transmission / reception system configured to measure a BER with the number of error bits of the specific pattern found when synchronizing a specific pattern (eg, 128-bit G and GB) when transmitting and receiving. We believe the quality of the channel is good.

Therefore, it is determined whether the selected baseband modulation and demodulation method is a baseband modulation and demodulation method that can form a transmission channel having the performance of the minimum BER range defined for each data to be transmitted, and using the best method among the determined baseband modulation and modulation methods. Transmit by channel defined according to personality.

That is, when data to be transmitted is input, the data determination unit 111 determines whether the input data is simple data or multimedia data. If the input data is simple data and is transmitted using the UHF band, the modulation / demodulation unit 112 modulates data including an OOK (On / Off Keying) modulation scheme as shown in FIG. 3, and the TDMA RF transceiver unit. In 120, the data is wirelessly transmitted through the UHF transceiver 122. If the input data is simple data and multimedia data that does not use the UHF band, the modulation / demodulation unit 112 compresses the data according to a predetermined compression format in the case of the multimedia data as shown in FIG. Thereafter, a data modulation process that does not include an OOK (On / Off Keying) modulation method is performed, and the transceiver 120 wirelessly transmits this data through the ISM transmitter / receiver 121.

On the other hand, in the case of receiving data, data is received through the ISM transmitter / receiver 121 in the case of simple data and multimedia data that do not use the weak radio waves of the UHF band according to the type of data received, and the weak UHF band. In the case of simple data using radio waves, since data is received through the UHF transceiver 122, a separate data determination process is not required. The data thus received is processed in the reverse order to the above transmission process. That is, in the case of simple data using weak radio waves in the UHF band, the data received through the UHF band transceiver 122 from the transceiver 120 is converted by the OOK (On / Off Keying) demodulation process in the modulator 112. The data is demodulated and converted to the original simple data. In the case of simple data and multimedia data that do not use the weak radio wave of the UHF band, the transceiver 120 is received through the ISM transceiver 121 so that a separate data determination process is not required. The received data is demodulated by a demodulation process that does not include an OOK (On / Off Keying) modulation scheme in the demodulation unit 112 and is reduced to original simple data and multimedia data through a process of decompression.
