4096-QAM

• See QAM (Quadrature Amplitude Modulation)
• The 4096-QAM is a specific case of M-ary QAM scheme in which a carrier wave of fixed frequency can exist in one of 4096 different states in the constellation plot.
• Each symbol consists of 12 bits out of 4096 different possible combinations.
• The total number of bits that can be used to modulate the carrier wave is 12.
• Since, this scheme uses binary data to perform modulation and demodulation like other relatively lower order QAMs (from 16 to 256), the number of combinations possible with 12 bits is 212 i.e. 4096.
• Or equivalently, the number of bits that can be accomodated as per equation 2 is log2 4096 = 12
