enhanced spectrum meaning in Chinese

增强的光谱
增强光谱

The convergences of these algorithms are proved in theory . their output signal - to - noise ( snr ) is derived and bigger than that of the traditional adaptive line enhancer ( ale ) . simulation with the torpedo - radiated data indicates that the proposed algorithms are much better than the ale and the short - time correlation based adaptive line enhancer ( scbale ) in suppressing gaussian noise and enhancing spectrum feature
对该算法的收敛性能进行了严格的证明，推导了该算法输出信噪比的计算公式，证明了该信噪比总是大于基于lms的自适应线谱增强器的输出信噪比，定义了评价算法性能的若干参数。
