Hence, in this half-duplex communication system there are 46 potential receiving nodes.
Each node is equipped with one omni-directional antenna and operates in the half duplex mode.
Communication was successful up to 38,400 bps on the computers in asynchronous half duplex mode, at packet sizes varying from 50 to 2000 bytes.
In this article, we consider a network with three relays operating in half duplex mode.
Considering a relay network with one source node S, two relay nodes R1 and R2, and one destination node D over a wireless multi-hop channel, where each relay node has one transmission antenna and two receiving antennas, and the source node and the destination node have a single antenna respectively, all nodes working in half duplex mode, as shown in Figure 1.
Traditionally, wireless communication nodes operate in half duplex (HD) mode, i.e., in either time division duplex (TDD) mode or frequency division duplex (FDD) mode.
We assume that the relays in this network are operated in the half-duplex mode and equipped with multiple antennas.
As stated, the relays operate in half duplex and cannot receive and transmit simultaneously.
We also assume that these systems operate in half duplex, i.e., RSs cannot receive and transmit data simultaneously.
We consider a 3-phase 2-way relay cooperative communication system consisting of three nodes: user A and its bilateral partner user B, as well as a relay R. All nodes operate in half duplex mode.
In this paper, the Gaussian two-way relay channel in the half-duplex mode, which operates in four phases, is studied.
