The __________ is the reduction,in decibels,to achieve a specified BER of an error-correcting coded system compared to an uncoded system using the same modulation.
A)FEC
B)Hamming distance
C)coding gain
D)checksum

Question

Quizplus · Accepted Answer

The given definition describes the term "coding gain," which is the reduction in decibels achieved by using error-correcting codes. Option A (FEC) also refers to error-correcting codes, but it doesn't specifically address the comparison between coded and uncoded systems. Option B (Hamming distance) is a measure of the minimum number of bit positions that must be changed to convert one code word into another, which is not directly related to the given definition. Option D (checksum) is a method for detecting errors in data transmission, but it doesn't involve error correction or coding gain.
