A basis function generation method of TDCS based on multi-threshold and its performance analysis
基于多级门限判决的TDCS基函数生成及性能分析

Concerning the lack of reflection of spectrum using level in traditional predefined threshold judgment of TDCS, a basis function generation method based on multilevel threshold judgment is proposed. The characteristics of spectrum in electromagnetic environment of TDCS and narrowband Gaussian noise are analyzed. And a binary hypothesis test, which is based on the introduction of multivariate judgment into the traditional binary method, is established so that the spectrum in electromagnetic environment can be quantized in multilevel to reflect the using levels of different bands. Simulation results show that this method has better performance on BER and anti-jamming compared with traditional predefined threshold judgment.
