← TechnologyWhich vulnerability emerges when a software-defined radio receives intentionally distorted quadrature amplitude modulation (QAM) signals?
A)Excess phase noise is suppressed
B)Message integrity becomes compromised✓
C)Adjacent channel leakage decreases
D)Overall amplifier efficiency increases
💡 Explanation
Message data integrity is compromised due to incorrect demodulation because signal processing interprets the distorted constellation points incorrectly. This is 'man-in-the-middle' attack via QAM interference, therefore the message cannot be trusted, rather than radio failure or signal boost elsewhere.
