QAMn

QAMn is a term that refers to Quadrature Amplitude Modulation with n bits per symbol. Quadrature Amplitude Modulation is a digital modulation technique used in wireless communication systems. It works by modulating both the amplitude and the phase of a carrier signal to transmit data. In QAMn, the "n" indicates the number of bits that are encoded into each symbol. This means that each symbol can represent 2^n different states. For example, in Quadrature Amplitude Modulation with 16 bits per symbol (QAM16), each symbol represents 2^16 = 65,536 different states. The greater the value of n, the more data can be transmitted at a given symbol rate. However, higher values of n also require more complex modulation and demodulation circuitry and are more susceptible to noise and interference. QAM is widely used in various communication standards, including Wi-Fi, cable modems, and cellular networks, due to its efficiency in spectrum usage. The specific implementation and parameters of QAMn can vary depending on the application and desired performance characteristics.
