Nonetheless, the sampling of PPM-UWB communication signal is limited by its ultra-wide bandwidth. According to the compressed sensing (CS) theory, the original signal can theoretically be under-sampled by a projection matrix with fewer rows than columns. However, the multiplication of matrix and signal demands that the received signal should already be sampled completely. The random matrix cannot be realized using hardware, and the process of random under-sampling is also uncontrollable. To address these problems, we propose a practical under-sampling method for the PPM-UWB communication signal based on CS theory and analog-to-information conversion (AIC) technology. Random matrix is replaced with AIC in the CS measuring projection stage, and the entire structure of AIC can be constructed using hardware. Whether or not the system matrix of AIC can satisfy the restricted isometry property is verified with the Johnson-Lindenstrauss lemma. Finally, a detection platform is constructed for the PPM-UWB communication signal based on CS and AIC, and it is considered for implementation. Although the proposed method cannot guarantee the precise reconstruction of a target vector, it can still be applied to under-sample the PPM-UWB communication signal practically. An analysis of performance results demonstrates the validity and applicability of the proposed method.
