Description: A channel,
M-ary input logic symbol x: s0, s1, ... sM-1
Y is a real value output
Channel, the following events occur:
a = f (x) to the real number one mapping, when x = si time, a = iA, A is a positive real number given to
y = a+ n, n is an obedience N (0, s2) distribution of independent random variables (with x independent, and each channel realization when n independently)
Write channel transition probability
If the input symbols, each channel shall appear, find the channel of mutual information I (X Y)
Draw mutual information changes under different SNR curve, with M as its argument, draw a cluster of curves (which add a AWGN channel capacity curve for comparison)
Adjustment function a = f (x), so that when x = si time, a = iA-b, b is also a real constant, at A and s the same circumstances, mutual information with the change of b is what trend ?
SNR curve with the impact of b values of mutual information?
