Title: Study on Estimation Method of OFDM Underwater Acoustic Channel Based on Compressed Sensing
Abstract: Two classical sparse signal reconstruction algorithms based on compressed sensing(CS) were briefly described: Matching Pursuit(MP) and Orthogonal Matching Pursuit(OMP).Combined with the order recursive algorithm of inverse matrix,for the high complexity of the OMP algorithms,an improved OMP algorithm based on order recursive was given,referred to as ORMP algorithm.The study found that the underwater acoustic channel impulse response is typical of sparse signals.The ORMP algorithm based on compressed sensing was applied to the underwater acoustic channel estimation.Simulation and sea trial experiments has verified the feasibility and superiority of the algorithm.
