Q
Which among the following factors affect the error rate?
AA. Encoding techniques
BB. Modulation scheme
CC. Channel capacity
DD. Access techniques
Correct Answer:
B. B. Modulation scheme
Explanation:
Wireless link errors are parameters of importance in characterizing the spectrum band. The modulation scheme and the amount of interference in the spectrum band influence the error rate. Wrongful sensing decisions are also a contributing factor to the high error rate.
