Which outcome occurs when a high bit error rate (BER) is introduced during digital signal processing in a wireless communication system?

💡 Explanation

Increased forward error correction (FEC) overhead occurs in order to combat the high BER, because FEC adds redundant data to correct errors introduced during transmission and processing; therefore, bandwidth efficiency decreases rather than SNR increasing, which would reduce errors.
