CWISA-102 · Question #3

What is the benefit of using SINR as opposed to SNR to reference signal quality at a receiver?

The correct answer is A. SINR includes interference as well as the noise floor. SNR (Signal-to-Noise Ratio): Measures the power of the desired signal relative to background SINR (Signal-to-Interference-plus-Noise Ratio): Considers both background noise and interference from other signals operating on the same frequency. Practical Importance: SINR is a more…

Question

What is the benefit of using SINR as opposed to SNR to reference signal quality at a receiver?

Options

  • ASINR includes interference as well as the noise floor
  • BSNR excludes the noise floor, which skews the results
  • CSINR excludes interference and only measures the noise floor
  • DSNR includes interference measurements that skew the results

Explanation

SNR (Signal-to-Noise Ratio): Measures the power of the desired signal relative to background SINR (Signal-to-Interference-plus-Noise Ratio): Considers both background noise and interference from other signals operating on the same frequency. Practical Importance: SINR is a more realistic indicator of real-world signal quality in wireless environments where interference is a significant factor.
