      Signal Redundancy Analysis Based on CoSaMP Algorithm

      摘要:
      以稀疏表示理论为出发点,分析信号的压缩感知理论与传统Nyquist采样定理的理论对比结果,根据CoSaMP算法和IFFT信号重构结果,定性和定量地分析了信号内部冗余性与利用这种冗余特征进行减运算量处理的可行性,进一步探讨信号的非均匀化处理,包括分数域和分形等方法在信号处理领域的适应性.
      Abstract:
      Aiming at the expansion of the new method of signal processing,from the sparse representation theory as the starting point,combining the signal compression perception theory with the traditional Nyquist sampling theorem,the internal performance of the signal is a great redundancy,and through CoSaMP Algorithm and IFFT transform,the results are analyzed and compared.The feasibility of the internal redundancy and the redundancy processing are analyzed qualitatively and quantitatively.Further,the nonuniformization of the signal includes fractional domain and fractal method will be in the signal processing and will be a great development.
