PROJECT TITLE :
Parallel Two-Way Relaying in Cooperative OFDMA Cellular Systems
We take into account a parallel two-means relaying orthogonal frequency division multiple access (PTWR-OFDMA) theme based mostly on analog network coding in that mobile terminals (MTs) are divided into close to-nodes (NNs) and way-nodes (FNs). An NN communicates with the base station (BS) directly while an FN communicates indirectly via the assistance of NNs. We tend to study the planning and analysis issues for PTWR-OFDMA. The proposed theme has some noticeable advantages. Initial, the throughput of PTWR-OFDMA increases like $ln K$, a lot of beyond that of $lnln K$ in conventional OFDMA ($K$ is the quantity of MTs). Second, PTWR-OFDMA can provide a lot of higher fairness than conventional OFDMA. Third, the power overhead per NN reduces quickly when $K$ will increase if there's a peak rate limitation, implying that there's no strong incentive for a few users to avoid providing relaying.
