WebFeb 14, 2024 · Background. The Nyquist formula gives the upper bound for the data rate of a transmission system by calculating the bit rate directly from the number of signal levels and the bandwidth of the system. Specifically, in a noise-free channel, Nyquist tells us that we can transmit data at a rate of up to. C = 2B log2 M C = 2 B l o g 2 M. WebJun 7, 2024 · This picture represents the bandwidth of the baseband signal. The symbol fs is the IQ Sample Rate. There are several meanings to bandwidth; you are familiar with the one used in data communication but for RF signals the bandwidth refers to the width of the box above. As the picture implies, your bandwidth is 0.8 times the IQ rate.

WebThe data rate is related to how quickly you can switch between f + Δ f and f − Δ f. Since you can't switch more quickly than f itself (the frequency of the carrier wave), the maximum theoretical bit rate is equal to the carrier wave frequency, and the bandwidth is f + 2 Δ f. If the bit rate is lower, say r, then the required bandwidth is r ...
