QAM Formats: 8-QAM, 16-QAM, 32-QAM, 64 ... - Electronics Notes QAM is in many radio communications and data delivery applications. However some specific variants of QAM are used in some specific applications and standards. There is a balance between data throughput and signal to noise ratio required. As the order of the QAM signal is increased, i.e. progressing from 16QAM to 64QAM, etc. the data throughput achievable under ideal conditions increases. However the downside is that a better signal to noise ratio is required to achieve this. For some systems the order of the modulation format is fixed, but in others where there is a two way link, it is possible to adapt the order of the modulation to obtain the best throughput for the given link conditions. The level of error correction used is also altered. In this way, changing the modulation order, and the error correction, the data speed can be optimised whilst maintaining the required error rate. For domestic broadcast applications for example, 64 QAM and 256 QAM are often used in digital cabl...
