Signal modulation envelope measurement procedure uses single sideband filtering in Fourier transform domain to calculate Complementary Cumulative Distribution Function

摘要

A signal modulation envelope measurement procedure samples (1) the input signal (S) performs a Fourier transform (2), filters out positive or negative frequencies to create a single sideband signal that is inverse transformed (4) calculates the logarithmic absolute value (5) or CCDF (Complementary Cumulative Distribution Function). Includes Independent claims for implementation as a computer program in digital memory.
