Application of 2-step QRM-MLD for MIMO-OFDM
あらまし マルチ送受信アンテナ(MIMO)空間多重を用いる直交周波数分割多重(OFDM)伝送の信号分離法とし て,QR 分解と M アルゴリズムを用いる演算量削減型最尤検出(QRM-MLD)が MLD に近い誤り率特性を達成するこ とが知られている.筆者らは以前,シングルキャリア(SC)伝送を対象に最小平均二乗誤差規範に基づく周波数領域 等化(MMSE-FDE)出力より事後確率を計算してシンボル候補を絞り込むことで演算量を削減する,2 ステップ QRM-MLブロック信号検出(QRM-MLBD)を提案した.2ステップQRM-MLD は SC伝送だけではなく,MIMO-OFDM 伝送にも適用できる.本稿では,MMSE 規範に基づく線形検出(MMSED)を第 1 ステップに用いる 2 ステップ QRM-MLD を MIMO-OFDM 伝送に適用する.QRM-MLD においては送信信号の検出...
متن کاملA Low-Power Adaptive MIMO Detector for MIMO-OFDM WLAN Systems
A MIMO-OFDM receiver requests high-speed MIMO detection to separate spatially multiplexed signals on real-time processing, which causes large power dissipation due to its high throughput performance. We present an adaptive MIMO detector which adaptively changes the computational speed of MIMO detection by estimating Doppler shifts correlated with fading channel variations. The adaptive detector...
متن کاملSingle-carrier Transmission Using Qrm-mld with Antenna Diversity
The frequency-domain received single-carrier (SC) signal can be expressed using the matrix representation similar to the multiple-input multiple-output (MIMO) multiplexing. The signal detection schemes developed for MIMO multiplexing can be applied to the SC transmissions. In this paper, we apply maximum likelihood detection employing QR decomposition and M-algorithm (QRM-MLD) to the SC signal ...

متن کاملA Thesis for the Degree of Master An Improved LLR Computation Algorithm for QRM-MLD in Coded MIMO Systems
For next generation wireless communication systems, multiple-input and multiple-output (MIMO) systems have been receiving a great attention due to the fact that use of multiple transmit and receive antennas dramatically increases the capacity and diversity. To achieve optimal performance for the MIMO detection, the maximum likelihood (ML) detector which minimize joint error probability is neces...
