Solve the following problem:
Consider the channel model shown in Figure and assume both channel components are BSC channels with crossover probability p = ½.
1. What is the ergodic capacity of this channel?
2. Now assume that the transmitter can control the state of the channel and the receiver has access to channel state information. What is the capacity of the resulting channel?
