Turbo QAM, or 256-QAM is a modulation method in which the two carrier signals are shifted in phase by 90 degrees. These two signals are then modulated and combined. The 90° difference in phase between the two signals means they are "in quadrature" | Turbo QAM, or 256-QAM is a modulation method in which the two carrier signals are shifted in phase by 90 degrees.

- | In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates. In reality, most claims of big increases in transfer rates are likely exaggerated. QAM links are more susceptible to noise. As a result, Turbo QAM is generally only useful in very low-noise/ | + | In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates.
