[Legacy Report] Parallel Two-Way Relaying in Cooperative OFDMA Cellular Systems
In this talk, the presenter will outline a parallel two-way relaying - orthogonal frequency division multiple access (PTWR-OFDMA) scheme based on analog network coding. With PTWR-OFDMA, the mobile terminals (MTs) are divided into near-nodes (NNs) and far-nodes (FNs). An NN communicates with the base station (BS) directly while an FN communicates indirectly via the assistance of NNs. The presenter will show that PTWR-OFDMA has some noticeable advantages. First, the throughput of PTWR-OFDMA increases like lnK, much higher than that of lnlnK for conventional OFDMA (K is the number of MTs). Second, PTWR-OFDMA can provide much better fairness. Third, the power overhead per NN reduces quickly when K increases if there is a peak rate limitation, implying that there is no strong incentive for some users to avoid providing relaying.
