This article mainly gives you a detailed description of the OFDM technology on the vro and gives you a detailed explanation. What about this technology? What is the basic working principle? In traditional multi-carrier communication systems, the entire system band is divided into several sub-channel carriers that are separated from each other ). There is a certain protection interval between carriers, and the receiver uses a filter to separate each su

energy. Tag An RFID device contains a silicon-based memory connected to an external antenna. Label without power supply. Passive tags obtain energy in the electromagnetic field generated by the reader, and then start to send modulation information. Data modulation (modulation of 0, 1) is completed by direct modulation or PSK or phase modulation. Demonstrate the hardware inside the NFC tag, where we can see the memory logic circuit and so on. The most common is the "passive" label

In traditional multi-carrier communication systems, the entire system band is divided into several sub-channels (carriers) that are separated from each other ). There is a certain protection interval between carriers, and the receiver uses a filter to separate each sub-channel and then receives the required information. This can avoid mutual interference between different channels, but at the expense of frequency utilization. In addition, when the num

Modulation and Demodulation TechnologyModulation is the process of processing the encoded information of a signal source into a form suitable for channel transmission. In general, the signal source encoding information (source) contains a DC component and a lower frequency component, called baseband signal . Baseband signals are often not used as transmission signals, so the baseband signal must be transformed into a band with a very high frequency relative to the baseband frequency to be suitab

I have encountered many character encoding problems in my text message projects over the past few months. After searching many materials, making a hand-made attempt, and giving tips, it seems that I am not so confused. I have made some summary to share with you (Please advise if there are any mistakes) First, we should regard the byte array as the carrier of string.The string used by dot net is unicode encoded. It also displays the string in the form
