Long Term Evolution-Advanced (LTE-Advanced) and other advanced technologies like IEEE802.16e and IEEE802.11g base their physical layer transmission on multiple input multiple output (MIMO). The concept of multiple antennas at both receiver and transmitter ends is attributed with advantages of spatial multiplexing and diversity, however, the Implementation on small size UEs has its own limitations...
In this paper, we consider a single-link cooperative communication system, where the half-duplex decode-and- forward (DF) relay does not have its own energy supply. Instead, it harvests energy from the interference and the signal received from the source and uses that harvested energy for relaying operation. For such systems, we develop joint optimal allocation of the transmit powers of the source...
In this paper, we consider optimal power allocation for conventional and buffer—aided link adaptive energy harvesting (EH) relay systems, where an EH source communicates with the destination via an EH decode—and—forward relay {over fading channels}. In conventional relaying, source and relay transmit signals in consecutive time slots whereas in buffer—aided link adaptive relaying, the state of the...
In this paper, we consider two-way decode-and-forward (DF) multiple access and time division broadcasting relaying protocols with energy harvesting (EH) nodes. We propose optimal offline joint energy and transmission time allocation schemes for the considered relaying protocols taking into account channel state uncertainty. The proposed joint energy and transmission time allocation schemes are obtained...
