1024-QAM

• See QAM (Quadrature Amplitude Modulation)
• The 1024-QAM is a specific case of M-ary QAM scheme in which a carrier wave of fixed frequency can exist in one of 1024 different states in the constellation plot.
• Each symbol consists of 10 bits out of 1024 different possible combinations.
• Thus, the total number of bits that can be accomodated in a symbol is 10.
• Since, this scheme uses binary data to perform modulation and demodulation like the relatively lower order QAMs (from 16 to 256), the number of combinations possible with ten bits is 210 i.e. 1024.
• Or equivalently, the number of bits that can be accomodated as per equation 2 is log2 1024 = 10.
