Regarding simu1: During the initialization process before running Simulink, channel time delay and amplitude estimation is completed. Multipath combining weight coefficients estimation employs optional EG/MR/MMSE combining schemes. Channel options include AWGN (Additive White Gaussian Noise) and IEEE 802.15.3a UWB standard channel models (CM1-CM4). For simplification, the simulation data package from IEEE 802.15.3a channel models is used here. The Eb/No parameter in the model refers to the energy per bit to noise power spectral density ratio. In AWGN channel, when Eb/No reaches 4.31 dB, the bit error rate is 0.01.

Extracting seven instantaneous information-based features from signals: maximum value of zero-centered normalized instantaneous amplitude power spectral density, standard deviation of zero-centered normalized instantaneous amplitude absolute value, standard deviation of absolute value of instantaneous phase nonlinear component in zero-centered non-weak signal segments, standard deviation of instantaneous phase nonlinear component in zero-centered non-weak signal segments, standard deviation of absolute value of zero-centered normalized instantaneous frequency in non-weak signal segments, maximum value of normalized instantaneous frequency power spectral density in a signal segment, and a novel feature parameter based on different projection characteristics of QPSK and 16QAM signals on the XI axis.
