You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: original_LLL_.m
    path of file: ./repos/MIMO_OFDM/第11章 空间复用的MIMO系统的信号检测/格基规约的MMSE检测
    
    the code of the file until where you have to start completion: function [Q,R,T] = original_LLL(Q,R,m,delta)
% Input parameters
%     Q : orthogonal matrix,  nRxnT
%     R : R with a large condition number
%     m : column length of H
%     delta : scaling variable
% Output parameters
%     Q : orthogonal matrix,  nRxnT
%     R : R with a small condition number
%     T : unimodular matrix
