摘要
Abstract
Considering that current signal detection based on compressed sensing does not effectively use amplitude information of sparse coefficient, this paper proposes a new method. Based on the orthogonal matching pursuit( OMP) algorithm,the concept of normalized residual is presented through analyzing trans-formation information of normalized residual. A two-dimensional(2D) signal detection algorithm is pro-posed in view of normalized residual and normalized remainder. Experiment results show that the effective threshold decreases continuously with the loss of signal-to-noise ratio( SNR) ,and the detection probability meets requirement under the condition of -8 dB SNR and 0. 25 compression ratio. The algorithm possesses a good adaptability.关键词
