← TechnologyWithin LTE cellular communications, which bottleneck limits signal quality during quadrature amplitude modulation?
A)Insufficient Channel Spectrum Allocation
B)Inadequate Receiver Noise Cancellation
C)Limited Computational Processing Power✓
D)Over-Amplified Signal Transmission Power
💡 Explanation
Limited processing during QAM causes inter-symbol interference (ISI) because the system struggles to quickly decode complex modulated signals. Insufficient computational power strains the FFT/IFFT operations, therefore errors increase during demodulation rather than efficient decoding in ideal conditions.
