Abstract: A method includes acquiring multiple pieces of first received signal quality information at a receiver, where the multiple pieces of first received signal quality information represent qualities of signals received at the receiver, generating first conditional sample statistical values based on the multiple pieces of first received signal quality information and phase shift arrays corresponding to the signals, determining the first phase shift array that meets a communication requirement according to the first conditional sample statistical values, where the first phase shift array includes the phase shift value for at least one reflective element of an IRS, and configuring the IRS based on the first phase shift array.

Abstract: An encoding method, a decoding method, an electronic device and a storage medium are disclosed. The encoding method includes: acquiring stored data in a storage system, and acquiring nodes corresponding to the stored data to obtain a number of the nodes; dividing the acquired stored data into a sequence of information vectors, and generating an information matrix according to the number of the nodes and a number of the sequence of information vectors; and calculating an encoded block according to each information vector and the information matrix to obtain a sequence of encoded blocks.
