the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolutionspectral estimation of target reflectivity.all seven (7)files should be downloaded for the simulation to work.(dls3D.m,estimate.m,get2S1Data.m,getConstraints.m, getImageData.m,getPixelData.m, getSLICYData.m)

These routines scramble an audio file by moving around short, overlapping windows within a local window. They can be used to create new versions of existing recordings that preserve the spectral content over longer time scales, but remove structure at shorter timescales. This can be useful e.g. for making speech unintelligible. Routines are also included to shuffle Gammatone subbands independently, for further scrambling.

设计了一种具有异周期毗邻结构的新型循环前缀,提出了相应的OFDM 频偏估计算法。该异周期毗邻结 构循环前缀由CP1 和CP2 两部分构成,使OFDM 符号具有双周期特征。通过引入较短的CP1 ,牺牲极少的资源, 可以有效克服现有频偏估计方法中的固定频偏估计范围的缺陷,同时具有频偏估计范围大,精度高的特点。(This paper proposes a heter2cycle abutted CP st ructure and a two2step OFDM carrier f requency calibration algorithm. The cyclic prefix of the new cyclic prefix is made up of CP1 and CP2 , which provide the character of double2cycle for OFDM symbol. By int roducing a short CP1 , the proposed algorithm can overcome the defect of fixed f requency off set estimation range in current f requency estimation method , and achieves larger f requency esti2 mation range while obtaining fine f requency calibration.)
