How can data rate be increased without increasing bandwidth?
- A.It is impossible
- B.Increasing analog-to-digital conversion resolution
- C.Using a more efficient digital code (correct answer)
- D.Using forward error correction
WhyData rate can be increased without increasing bandwidth by using a more efficient digital code. Data rate can be increased without increasing bandwidth by using a more efficient digital code, one that packs more bits of information into each symbol transmitted, answer C. It isn't impossible, and increasing ADC resolution or adding forward error correction don't directly increase the data rate carried within a fixed bandwidth the way a more efficient coding scheme does.
