Which of the following is not used to improve received signal quality

1.	Which of the following is not used to improve received signal quality over small scale times and distance?(a) Modulation(b) Equalization(c) Diversity(d) Channel codingThe question was asked during an interview.The origin of the question is Fundamentals of Equalization topic in portion Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» Correct ANSWER is (a) Modulation To explain: Equalization, DIVERSITY and channel CODING are the three techniques which are used to improve received SIGNAL quality and link performance over small scale times and distance. But, the approach, cost, complexity and EFFECTIVENESS varies in wireless communication system.
