Achievable rate regions and outer bounds for a multi-pair bi-directional relay network
In a bi-directional relay channel, a pair of nodes wish to exchange independent messages over a shared wireless half-duplex channel with the help of relays. Recent work has mostly considered information theoretic limits of the bi-directional relay channel with two terminal nodes (or end users) and one relay. In this work we consider bi-directional relaying with one base station, multiple termin...
متن کاملAnalog Network Coded SC/OFDM Hybrid Bi-Directional Relay Communications Using Adaptive Modulation and Coding
あらまし 伝搬損失およびシャドウィング損失の影響を低減しつつ直接通信と等しい最大スループットを実現 する手段として,アナログネットワーク符号化(ANC)を用いる双方向中継通信が注目されている.我々はこれま で,ANC を用いるシングルキャリア(SC)双方向中継通信を対象に検討を行なってきた.しかしながら,ANC で は,重ね合わせられて受信された上下リンクの信号をそのまま増幅・中継するため,上下リンクで等しい伝送方式 を用いる必要はない.したがって上下リンクそれぞれに適した伝送方式を用いることにより,さらなるスループッ トの改善が期待される.そこで本稿では,上りリンクでは SC 伝送を,下りリンクでは直交周波数分割多重(OFDM) 伝送を用いて ANC 双方向中継通信を行う SC/OFDM ハイブリッド ANC 双方向中継通信について検討している.ま た端末および基地局送信機では,上...
متن کاملJoint Transmit/Receive MMSE-FDE for Analog Network Coded Single-Carrier Bi-directional Multi-Antenna Relay
In this paper, joint transmit/receive frequency-domain equalization (FDE) is proposed for analog network coded (ANC) singlecarrier (SC) bi-directional multi-antenna relay. In the proposed scheme, diversity transmission using transmit FDE is performed at relay station (RS) equipped with multiple antennas while receive FDE is carried out at base station (BS) and mobile terminal (MT) both equipped...
متن کاملA Single-Fiber Bi-directional Self-Healing WDM Metro-Ring Network with Bi-directional OADM
We propose and demonstrate a single-fiber bi-directional WDM self-healing ring network with simple bidirectional OADM. By employing our proposed alternate-path switching scheme, the bi-directional traffic can be restored promptly under single fiber failure. Introduction Bi-directional wavelength division multiplexing (WDM) self-healing ring (SHR) network [1-2] is an attractive and cost-effectiv...
متن کاملAcquired sensorimotor coordinated signal transformation in a bi-directional neural network model
In general, a biological neural system is divided into two major paxts, one is a neural system for motor control and the other is that for sensory reception, and they are working not independently but cooperatively to perform various kinds of complex activities. Therefore its disorders make something strange phenomena. In the previous study, it is observed that a sensorimotor coordinated neural...
