MIMO RECIEVER AND QR DECOMPOSITION AND MULTI DIMENSIONAL DETECTION USED THE MIMO RECEIVER

摘要

A MIMO(Multi Input Multi Output) receiver and a QR decomposition device used in the MIMO receiver and a method thereof and a multi dimensional detection device and a method thereof are provided to repeat a part of rows, parallel process symbol detection in a multi dimensional detection process at the same time and reduce a process delay time in a multi dimensional receiving process. A QR decomposition unit performs QR decomposition about nT-n-1 from 1. The QR decomposition unit performs QR decomposition through row exchange about nT from nT-n. A multi dimensional detection unit calculates the first distance values for detecting an m numbered symbol about the first R matrix and the second distance values for detecting an m-numbered symbol about the second R matrix. The multi dimensional detection unit simultaneously detects an m numbered symbol and an m-1 numbered symbol through the first and second distance values.
