Suppose that binary PSK is used for transmitting information over an AWGN with a power spectral density of N, 1010 W/Hz. The transmitted signal energy is & A'T, where 7 is the bit interval and A is the signal amplitude. Determine the signal amplitude required to achieve an error probability of 10 when the data rate is (a) 10 kbits/s, (b) 100 kbits/s, and (c) 1 Mbit/s.
