In this paper, a Two-way Decode and Forward Relaying for orthogonal frequency division multiple access (OFDMA) mobile systems (TWR-DF-oFdMA) is proposed.
In this paper, a two way decode and forward (DF) system employing maximum ratio transmission (MRT) technique is studied.
This paper investigates the two-way relay transmission over orthogonal frequency division multiplexing (OFDM) channels using digital network coding. For a given ...
The relay networks combined with OFDM can improve the system capacity and reliability [2-4]. There are two main relay methods, amplify-and-forward. (AF) and ...
In this paper, we formulate the scheduling problem in AF two-way half-duplex relay assisted OFDMA systems as an op- timization problem. By using dual ...
The scheme has lower complexity and better spectral efficiency when compared to DF relaying scheme. Reference [17] proposed the hybrid downlink and uplink NOMA ...
Oct 9, 2015 · Processing of signal at RN relies on different processing functions, such as amplify-and-forward (AF), decode-and-forward (DF), etc., among ...
Simulation results show that substantial system throughput gains are achievable by the proposed two-way relaying and optimal resource allocation schemes ...
We consider a parallel two-way relaying orthogonal frequency division multiple access (PTWR-OFDMA) scheme based on analog network coding in which mobile ...
