← TechnologyWhich risk noticeably increases when multi-path interference excessively distorts the OFDM training signal?
A)Equalization performance will degrade sharply✓
B)Carrier frequency offset intensifies greatly
C)Signal transmission latency is severely reduced
D)Non-linear noise accumulation becomes significant
💡 Explanation
Because the training symbols rely on known sequences, distorted reception from multi-path interference degrades channel estimation using the least squares estimation mechanism; therefore, downstream equalization fails rather than other issues which affect performance differently under distinct constraints.
