Webb4 sep. 2024 · In data communication, we usually prefer the average case and the relationship between data rate and signal rate is S = c × N × 1 r baud where N is data rate, c is case factor, S is no number of signal elements and r is previously defined ratio. I don't understand what the above formula signifies. Webb4 feb. 2024 · This is according to the Shannon theorem rdata = BW x log2 (1+SNR) (max data rate rdata is equal to the bandwidth, BW, multiplied by the base-2 logarithm of the SNR plus 1). On the other hand, at a low SNR, the max data rate increases almost linearly. Therefore, it is not efficient aiming only to obtain a high SNR.
