Adaptive OFDM Index Modulation for Two-Hop Relay-Assisted Networks
In this paper, we propose an adaptive orthogonal frequency-division multiplexing (OFDM) index modulation (IM) scheme for two-hop relay networks. In contrast to the traditional OFDM IM scheme with a deterministic and fixed mapping scheme, in this proposed adaptive OFDM IM scheme, the mapping schemes between a bit stream and indices of active subcarriers for the first and second hops are adaptive...
متن کاملAn Approximation of the Outage Probability for Multi-hop AF Fixed Gain Relay
In this letter, we present a closed-form approximation of the outage probability for the multi-hop amplify-andforward (AF) relaying systems with fixed gain in Rayleigh fading channel. The approximation is derived from the outage event for each hop. The simulation results show the tightness of the proposed approximation in low and high signal-to-noise ratio (SNR) region.
متن کاملSNR Maximization at CSI Aware AF Relay Assisted Networks
Manuscript Received 8-August-2012 and revised 5-October-2012 ISSN: 2322-3936 Accepted on 1November-2012 Abstract— This paper concerns two-hop communication over relayassisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) ...
متن کاملEnergy Efficient OFDM Transmission Scheme based on Continuous Phase Modulation
In this paper we propose an energy efficient OFDM transmission scheme. Two CPM (continuous phase modulation) schemes are introduced to OFDM, keeping in view the constant envelope and continuous phase changing nature of CPM modulation. Energy efficiency of the proposed scheme is investigated by simulating peak to average power ratio (PAPR), and is compare with the conventional OFDM scheme. The i...
متن کاملSNR Maximization at CSI Aware AF Relay
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...
