To address the problem of unbalanced received signal-to-interference-and-noise ratio (SINR) at relay and destination nodes in wireless power transfer (WPT)- supported relay system, we propose a novel asymmetric full-duplex (FD) decode-and-forward (DF) WPT relay strategy, where the transmission time slots are not necessarily identical. By introducing asymmetric time slots, higher degree of freedom...
In this paper, we study the power consumption in relay networks of the 60 GHz wireless communication based on amplify-and-forward (AF) and decode-and-forward (DF) relaying strategies. We propose a total power consumption model including drive power, decoding power, and power consumption of power amplifier (PA). This model is formulated as a function of drive power, which gives an easy access to the...
An asymmetric resource allocation (ARA) scheme for the downlink wireless multi-destination relay systems with orthogonal frequency division multiplexing (OFDM) modulation is proposed. Unlike the previous work, the transmission durations at the source (base station) and the relay are designed to be asymmetric, which enhances the degree of freedom for transmission. Therefore, the proposed ARA scheme...
We investigate asymmetric resource allocation (RA) for a dual-hop multi-relay decode-and-forward (DF) relay system based on the orthogonal frequency division multiplexing (OFDM) modulation, where given a fixed total transmit time duration, the time slot durations for the two hops via each of the K relays are designed to be asymmetric, and in general, all the 2K time slot durations may be different...
