说明： 为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环
谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频
率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信
噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in
the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2
tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2
able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the
decision threshold correspond to different false alarm probability , as a result , making the sensing users
can detect licenced users signal under lower signal in noise ratio (SNR) .)

decomp_reconst_W
Decompose image into subbands, denoise using BLS-GSM method, and recompose again.
fh = decomp_reconst(im,Nsc,filter,block,noise,parent,covariance,optim,sig)
im: image
Nsc: number of scales
filter: type of filter used (see namedFilters)
block: 2x1 vector indicating the dimensions (rows and columns) of the spatial neighborhood
noise: signal with the same autocorrelation as the noise
parent: include (1) or not (0) a coefficient from the immediately coarser scale in the neighborhood
covariance: are we considering covariance or just variance?
optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0)
sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise)
Version using a critically sampled pyramid (orthogonal wavelet), as implemented in MatlabPyrTools (Eero).
