Latest Patents
Kezhou Li holds a patent titled "Method for calculating causal impulse response from a band-limited spectrum." This computer-implemented method enhances the calculation of a time-domain impulse response with improved causality. The process begins with a first spectrum in the frequency domain, which may be band-limited. The method calculates a first time-domain impulse response from this spectrum and removes any non-causal portions to obtain a second time-domain impulse response. Furthermore, it calculates a second spectrum of the second time-domain impulse response and modifies it by adding a causal signal to minimize the difference between the second and first spectra. Ultimately, the method calculates the time-domain impulse response with improved causality from the modified second spectrum.
