How Do You Calculate Channel Capacity?

How Do You Calculate Channel Capacity? According to channel capacity equation, C = B log(1 + S/N), C-capacity, B-bandwidth of channel, S-signal power, N-noise power, when B -> infinity (read B ‘tends to’ infinity), capacity saturates to 1.44S/N. How is channel capacity calculated in wireless communication? Capacity is given as follows (Dong and Vuran, 2013a):
