Your task is to transmit data from one computer to another through an AWGN channel. For this purpose you employ a bipolar binary signal that is a +1 V or a ?1 V pulse during an interval [0, T ] depending on whether the information bit is a 0 or a 1. The power spectral density of the noise added to the signal in the channel is kT/2 = 10?3 W/Hz. Since you are transmitting important messages over this system, you require that you obtain at most 100 errors in every 125 Kbyte file. Determine the maximum rate at which you can transmit bits over this channel. [Hint: The average probability of error of this system or BER is (number of bits in error)/(total number of bits sent).
