Hola, la letra es:
"Using two channels at once. Consider two discrete memoryless channels (X1, p(y1 |
x1),Y1) and (X2, p(y2 | x2),Y2) with capacities C1 and C2 respectively. A new channel
(X1 ×X2, p(y1 | x1)×p(y2 | x2),Y1 ×Y2) is formed in which x1 " X1 and x2 " X2, are
simultaneously sent, resulting in y1, y2. Find the capacity of this channel."
Se puede resolver este ejercicio de otra forma sin usar que :
Y1 & X1 & X2 & Y2 forman una cadena de Markov ??
