Detecting method and apparatus for multiple transmitted signal

Abstract

The embodiment of the invention provides a method and a device for detecting multiple emission signals, which are is applied to solving the problems of high computational complexity or relatively large storage space is required when detecting multiple emission signals. The method comprises the steps that: signals which comprising multiple emission signals, channel alluvial response and white noise are received; the signals received are carried out space time matched filtering treatment to obtain sufficient statistics y of the signals received and a channel correlation matrix H is obtained according to the sufficient statistics y and a channel model; with respect to the y, H is in Krylov subspace to calculate multi emission signals. The embodiment of the invention can reduce computational complexity by calculating in the Krylov subspace.

Description

A method and device for detecting multiple transmitted signals technical field The present invention relates to a communication technology, in particular to a multi-transmit signal detection method and device. Background technique Multiple transmit signal detection technology refers to the detection of multiple transmit signals received at the same time. This technology uses factors such as spreading codes, time, signal amplitude, and phase combination of multiple transmit antennas to detect multiple transmit signals. The research on multiple emission signal detection theory originated in the early 1980s. After more than 20 years of development, multiple emission signal detection technology has reached a relatively mature level in theory. At present, the main research direction of multiple emission signal detection technologies is gradually developing from the theoretically optimal structure to the engineering sub-optimal structure, with the purpose of finding a solution t...
