Coded OFDM-IM With Transmit Diversity

open access: yesIEEE Transactions on Communications, 2017
In this paper, we propose a simple transmit diversity scheme for orthogonal frequency division multiplexing (OFDM) with index modulation (IM) in order to achieve a diversity gain for index detection, which can significantly improve the performance of ...

Achieving Transmit Diversity in OFDM-IM by Utilizing Multiple Signal Constellations

open access: yesIEEE Access, 2017
Orthogonal frequency division multiplexing (OFDM) index modulation (IM) is a novel multicarrier modulation, which employs both the indices of the active subcarriers and conventional constellation symbols to convey information.

A differential detection scheme for transmit diversity [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2000
We present a transmission scheme for exploiting diversity given by two transmit antennas when neither the transmitter nor the receiver has access to channel state information. The new detection scheme can use PSK constellations and encoding is simple. At the receiver, decoding is achieved with low decoding complexity.

Acute SARS-CoV-2 infections harbor limited within-host diversity and transmit via tight transmission bottlenecks

open access: yesPLoS Pathogens, 2021
The emergence of divergent SARS-CoV-2 lineages has raised concern that novel variants eliciting immune escape or the ability to displace circulating lineages could emerge within individual hosts. Though growing evidence suggests that novel variants arise

On the Beneficial Roles of Fading and Transmit Diversity in Wireless Power Transfer With Nonlinear Energy Harvesting [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2018
We study the effect of channel fading in wireless power transfer (WPT) and show that fading enhances the RF-to-DC conversion efficiency of nonlinear RF energy harvesters. We then develop a new form of signal design for WPT, denoted as transmit diversity,
