We wish to transmit a digital voice at 32 kbps through a communication channel having bandwidth of 3000 Hz. The received signal to noise power ratio is 30 dB. State which of the following statement is true:
A. To transmit data error-free through this channel, channel equalizer circuit should be used at the receiver
B. To transmit data error-free through this channel, the voice signal should be compressed by 2
C. To transmit data error-free through this channel, a channel code with coding gain of 3 dB should be used
D. It is not possible to transmit data error-free through this channel
