4FSK Modulation and Demodulation Communication Link MATLAB Bit Error Rate Simulation
Four-level Frequency Shift Keying (4FSK) is an important branch of digital modulation technology, representing four-level symbols (each symbol carries 2 bits of binary information) through four different frequency carrier signals. It is widely used in fields such as wireless communication and industrial control. Its core advantages lie in strong anti-interference capability and low implementation complexity, … Read more
