Signal sampling recovery method, apparatus and OvXDM system applied to OvXDM system

摘要

This application has disclosed a signal sampling recovery method, apparatus and OvXDM system applied to the OvXDM system. In the above method, based on the design parameters, one observation matrix Φ not related to the original signal y is constructed, wherein the observation matrix Φ is a two-dimensional matrix having a size M*S, and S is the original signal y. Length, M is less than S, the formulaCompressed signal Y_cs of size M*1 is obtained by compressing the original signal y at a relatively small sampling rate based on, where Y is a column vector of size S*1 obtained from the original signal y. , And reconstructing the compressed signal Y_cs according to a predetermined algorithm to recover the original signal y. This application is in the context of lowering the sampling rate of the system and accurately recovering the original signal, thereby lowering the system hardware specification requirements and improving the implementation of the scheme.
