—We show that the performance of relay selection can be improved by employing relays with buffers. Under the idealized assumption that no buffer is full or empty, the best source-relay and the best relay-destination channels can be simultaneously exploited by selecting the corresponding relays for reception and transmission, respectively. The resulting(More)
We propose a new relaying scheme referred to as space full-duplex max-max relay selection (SFD-MMRS), which uses relay selection and half-duplex (HD) relays with buffers to mimic full-duplex (FD) relaying. SFD-MMRS allows the selection of different relays for reception and transmission, which, in turn, enables the relays selected for reception and(More)
—In this paper, the problem of channel equalization in filter bank multicarrier (FBMC) transmission based on the offset QAM (OQAM) subcarrier modulation is addressed. Finite impulse response (FIR) per-subchannel equalizers are derived, based on the frequency sampling (FS) approach, both for the single-input multiple-output (SIMO) receive diversity and the(More)
Energy harvesting (EH) nodes can play an important role in cooperative communication systems which do not have a continuous power supply. In this paper, we consider the optimization of conventional and buffer–aided link adaptive EH relaying systems, where an EH source communicates with the destination via an EH decode–and–forward relay. In conventional(More)
Most of the existing literature on cooperative relay networks has focused on frequency– nonselective channels or frequency–selective channels with multi–carrier transmission. However , several practical systems employ single–carrier transmission over frequency–selective channels and the design of corresponding relaying schemes is a largely under–explored(More)
