Signal subspace identification is a crucial first step in many hyperspectral processing algorithms such as target detection, change detection, classification, and unmixing. The identification of this subspace enables a correct dimensionality reduction, yielding gains in algorithm performance and complexity and in data storage. This paper introduces a new minimum mean square error-based approach to infer the signal subspace in hyperspectral imagery. The method, which is termed hyperspectral signal identification by minimum error, is eigen decomposition based, unsupervised, and fully automatic (i.e., it does not depend on any tuning parameters). It first estimates the signal and noise correlation matrices and then selects the subset of eigenvalues that best represents the signal subspace in the least squared error sense. State-of-the-art performance of the proposed method is illustrated by using simulated and real hyperspectral images.

additive_noise_channel
模拟噪声的程序,可以根据需要改写,主要功能是实现噪声模型
(Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details:
op_channel = additivenoise(input_signal)
mathematical Model:
s(t) input signal to channel (=sig_ip)
n(t)additive random noise process added by channel (=noise_mat)
a(t) attenutation factor , here it is taken as random(=att_fact)
out put signal r(t) = a .* s(t)+ n(t)
an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal
