WebTwo different types of demodulation reference signals can be configured, type 1 and type 2, differing in the mapping in the frequency domain and the maximum number of orthogonal reference signals. Type 1 can provide up to four orthogonal signals using a single-symbol DM-RS and up to eight orthogonal reference signals using a double-symbol DM-RS. WebJun 27, 2024 · Demodulation. When digital information is transmitted over an analog medium, such as a telephone line, an electronic waveform is modulated to contain the information. This analog signal is called a carrier wave. Demodulation is the act of extracting digital data from this signal once it reaches its destination.
