Let me talk about the conclusion:
Quantification and normalization can function to reduce the signal dynamic range.
Scenario:
1, doing a spread spectrum systems capture time,
Two commonly used methods are: an FFT frequency domain and non-coherent accumulation time domain to find the maximum value .
Principle that both methods of selecting the maximum value accumulated received sequence, relative to the capture threshold value is determined.
The signal to noise ratio is dynamic, so the cumulative obtained peak is dynamic, which is to determine the capture threshold has brought some difficulties.
Quantized or normalized peak effect is to reduce the dynamic range, which is equivalent to a threshold noise cards low SNR, the signal at high SNR card!
2, the OFDM reducing PAPR operation, but also the value of the analog signal is normalized to the operation on the circumference also acts to reduce the dynamic range, i.e., to reduce the PAPR.
