Throughput Performance of Hybrid ARQ in MIMO-OFDM
Dept. of Electrical and Communication Engineering, Graduate School of Engineering, Tohoku University 05 Aza-Aoba, Aramaki, Aoba-ku, Sendai, 980-8579 Japan E-mail: †{nakajima, deep}@mobile.ecei.tohoku.ac.jp, ‡[email protected] Abstract Recently, Multi-Input Multi-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are gaining much attention for very high speed data communi...
متن کاملThe throughput of hybrid-ARQ protocols for the Gaussian collision channel
In next generation wireless communication systems, packet-oriented data transmission will be implemented in addition to standard mobile telephony. We take an informationtheoretic view of some simple protocols for reliable packet communication based on \HybridARQ", over a slotted multiple access Gaussian channel with fading and study their throughput (total bit/s/Hz) and average delay under idea...
متن کاملThroughput of Hybrid ARQ in Single-carrier MIMO Multiplexing
あらまし 最近,超高速伝送技術としてマルチ送受信アンテナ(MIMO)多重が注目されている.しかし,遅延時間 の異なる多数のパスから構成される周波数選択性フェージングチャネルにおいてシングルキャリア伝送では符号間 干渉により伝送特性が大幅に劣化する.そこで,筆者らはこれまでに,シングルキャリア伝送を対象として周波数 領域等化と並列干渉キャンセルを繰り返す周波数領域繰り返し並列干渉キャンセラ(PIC)を用いる MIMO 多重につ いて検討をしてきた.ところで,今後の移動通信ではパケット伝送が主流になることが予想され,誤り訂正符号化 と自動再送(ARQ)とを組み合わせたハイブリッド ARQ(HARQ)が重要な技術になる.そこで本論文では,シングル キャリア MIMO 多重に周波数領域繰り返し PICを適用したときの HARQ のスループット特性を計算機シミュレー ションにより明らかにしてい...
متن کاملThroughput analysis of nonbinary type-II hybrid ARQ
Nonbinary type-I1 hybrid ARQ (HARQ), which combines shortened Reed-Solomon (RS) code with ARQ, is proposed. Its throughput is obtained by extending Lin and Yu's analysis of binary type-I1 HARQ. Analytical results show that nonbinary HARQ outperforms its binary counterpart in throughput over Rayleigh fading channels when the modulation scheme and the FEC subsystem are selected properly. I . I N ...
متن کاملHybrid ARQ Throughput Performance of Multicode DS-CDMA MIMO Multiplexing
One of the promising techniques to allow highspeed data transmission with a limited bandwidth is multiinput multi-output (MIMO) multiplexing. As a signal separation scheme, an iterative frequency-domain interference cancellation (FD-IC) using two-dimensional minimum mean square error (2D-MMSE) frequencydomain equalization (FDE) was recently proposed. There are two types of FD-IC: parallel FD-IC...
