In digital communications, interleaving is classified as a type of ________ diversity.
Multiple Choice Options
- A✓ Correct Option
Time diversity
- B
Frequency diversity
- C
Space diversity
- D
Power diversity
Detailed Technical Solution & Explanation
Interleaving separates adjacent symbols in time before transmission. Because channel fading bursts typically affect consecutive time intervals, de-interleaving at the receiver disperses burst errors across time into isolated single-bit errors, providing Time Diversity.
Option Analysis:
•
Option A (Time diversity): Correct. Scrambles symbols across time to combat burst errors.
•
Option B (Frequency diversity): Transmits signals over multiple distinct frequency carriers.
•
Option C (Space diversity): Employs multiple physically separated antennas (MIMO).
•
Option D (Power diversity): Not a standard wireless diversity classification.
