(a) Consider voice transmission over a telephone line. Each channel has a bandwidth B = 3 kHz. We assume the analogue channel distorted by Additive White Gaussian Noise (AWGN). If the power signal-to-noise ratio is 20 dB, what is the channel capacity? (b) Consider Wideband Code Division Multiple Access (W-CDMA). For a given band- width B = 5 MHz, and transmission data rate of 25 kbps (kbits/sec), what is the required signal-to-noise ratio in decibel (dB)?
