Signal Detection Method Based on Compressed Sensing
Huang Jihai · Video Engineering · 2012
A novel detection method is proposed with the sparse signal characters.Firstly,the method transforms conventional channel estimation into non-complete reconstruction,which makes adaptability of channel estimation possible and reduces the complexity of channel estimation with lesser pilot signal and higher frequency spectrum utilization.Secondly,compressed rake combination is used with lower complexity.At last,the result of compressed correlation is used to judgment.Theoretical analysis and simulations are used to illustrate its validity and feasibility.
