← TechnologyWhich risk increases when spread spectrum's pseudorandom code period shortens?
A)Higher probability of code collision✓
B)Increased processing gain at receiver
C)Reduced interference in channels
D)Improved Doppler shift compensation
💡 Explanation
A shortened pseudorandom code period in spread spectrum raises code collision risk because the code repeats more often, therefore, multiple transmitters might use similar codes simultaneously, rather than maintaining near-orthogonality with longer uniquely random sequences.
