Consider a Gaussian channel with noise power spectral densit

Consider a Gaussian channel with noise power spectral density of 10^-12 Watts/Hz. Suppose that the transmission power over this channel is 10 Watts. Suppose that the channel\'s bandwidth is 10kHz. What is the maximum bit rate for which the probability of error approaches zero exponentially fast? Repest, Part a) When the channel has unlimited bandwidth.

Solution

The greater is the Bandwidth higher is the bit rate, When the bandwidth of the channel is unlimited the received signal has max bit rate. However other factor such as transmitting medium receiver may effect the bit rate.
