WebbWe will prove this result by use of Shannon’s random code ensemble and a suboptimal decoding technique called typical-set decoding. Shannon’s random code ensemble may be deﬁned as follows. Let S x = P/2W be the allowable average signal energy per symbol (dimension), let ρ be the data rate in b/2D, and let N be the code block length in ... WebbSolution First, we use the Shannon formula to find the upper limit. Example 3.41 The Shannon formula gives us 6 Mbps, the upper limit. For better performance we choose something lower, 4 Mbps, for example. Then we use the Nyquist formula to find the number of signal levels.
