Web(f) Channel capacity is the maximum, over all possible input distributions, of the mu-tual information that the channel establishes between the input and the output. So one lower bound estimate is simply any particular measurement of the mutual information for this channel, such as the above measurement which was 3/8 bits. 6 WebOct 1, 2014 · In this case the mapping π is simply π (z) = a i if z ∈ ]z (i−1)/q , z i/q ], where z i/q is the i th q-quantile 5 of the Gaussian distribution, with z 0 = −∞, z 1 = ∞. For asymmetric ...
