Which among the following factors affect the error rate?(a) Encoding t

1.	Which among the following factors affect the error rate?(a) Encoding techniques(b) Modulation scheme(c) Channel capacity(d) Access techniquesThe question was posed to me in a job interview.This question is from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio
Answer» The CORRECT answer is (B) Modulation scheme The best 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.
