Abstract
A signal detecting method and device are disclosed. The method includes: obtaining a matched filtering signal; determining a filtering matrix; decomposing the filtering matrix to obtain a principal diagonal matrix and a non-principal diagonal matrix; obtaining a parameter matrix and a parameter vector according to the principal diagonal matrix, the non-principal diagonal matrix, and the matched filtering signal; obtaining an iterative parameter and an iterative initial value according to the parameter matrix and the parameter vector; and performing an iterative calculation according to the iterative parameter and the iterative initial value; if the number of iterations reaches a preset number, obtaining an iterative final value, and obtaining an input of a decoder according to the iterative final value. The signal detection method may reduce the computational complexity and bit error rate, improve data throughput, and more advantageous for use in a large-scale multi-input multi-output system.
