基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the differen

谱减法是一种比较简单的语音降噪的方法，在语音信号具有较高的信噪比的情况下具有良好的降噪功能。 -Spectral subtraction is a relatively simple pronunciation methods of noise in speech signal with high signal-to-noise ratio (SNR) of cases with good noise function.

SNR largest independent component analysis algorithm, Face Recognition light treatment method, Energy spectrum analysis and calculation.

Including AHP, factor analysis, regression analysis, cluster analysis, For lack of EMD, SNR largest independent component analysis algorithm.
