Three of the most common digital modulation schemes you’ll see in specifications are Frequency Shift Keying (FSK), Amplitude Shift Keying (ASK), and LoRa (Long Range). To wrap my mechanically ...

A higher wave is interpreted as a 1 and a normal wave is interpreted as a zero. By changing the wave, the RFID tag can communicate a string of binary digits to the reader. Computers can interpret ...

was proposed for converting two-dimensional multiple-quadrature amplitude modulation (MQAM) signals to multiple-phase shift keying (MPSK) signals. This method leverages the unique properties of ...
