New Results on Transceiver Design for Two-Hop Amplify-and-Forward MIMO Relay Systems With Direct Link Abstract? Conventional amplify-and-forward (AF) protocol for half-duplex two-hop multiple-input?multiple-output (MIMO) relay systems assumes that the source node transmits the signal only at the first time slot. While making the source node silent at the second time slot simplifies the system design,…

OFDM Receiver Structure for a Subband-Selective Mitigation of Time-Variant Interference Abstract? System performance of orthogonal frequency-division multiplexing (OFDM) degrades in the presence of time-variant frequency-selective interference. In the literature, several pulse-blanking concepts have been introduced over the past few years, which are promising ways to mitigate impulsive interference for OFDM reception. However, blanking yields an…

On the Achievable Rate of OFDM With IndexModulation Abstract? Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a recently developed transmis-sion technique that extends the principle of spatial modulation to OFDM sub carriers.In this paper,the performance of OFDM-IM is studied in terms of the achievable rate assuming an -ary constellation and that channel state…
On the Performance of Non-Orthogonal Multiple Access in 5G Systems with Randomly Deployed Users Abstract-In this letter, the performance of non-orthogonal multiple access (NOMA) is investigated in a cellular downlink scenario with randomly deployed users. The developed analytical results show that NOMA can achieve superior performance in terms of ergodic sumrates; however, the outage performance…
On the Performance of Spatial Modulation: Optimal Constellation Breakdown Abstract?Spatial modulation (SM) is a new transmission technique for multi-antenna systems in which the transmit antennas are used to modulate the signal. In this paper, the symbol error rate (SER) performance of SM is investigated. In SM, a signal domain modulation (i.e. amplitude-phase modulation) and an…

Outage Probability of Energy Harvesting Relay-Aided Cooperative Networks Over Rayleigh Fading Channel Abstract? Energy harvesting technique is a potential way for relay node energy supply in cooperative networks with respect to deployment flexibility and maintenance charge reduction. However, unlike traditional power source, it is intuitive that the fluctuation of harvested energy flow can degrade the…
