TLDR
In this paper, a method for diversity transmission and reception for channels with intersymbol interference is presented, in which one can transmit from two or more antennas in such a way that a receiver with one or multiple antennas can benefit from the difference in channels from the transmit antennas to the receiver antenna(s).Abstract:
A method for diversity transmission and reception for channels with intersymbol interference is created With this method one can transmit from two or more antennas in such a way that a receiver with one or more antennas can benefit from the diversity offered by the difference in channels from the transmit antennas to the receiver antenna(s) The way the transmission and reception is organized makes it relatively simple to in the receiver detect the transmitted symbols despite intersymbol interference in the channel Due to the increased diversity experienced by the receiver the average power level required at the receiver is reduced which can be used to increase the capacity or coverage of a wireless network and/or reduce the required transmitted powerread more

Basestation modulation diversity for digital simulcast
TL;DR: A base station modulation diversity scheme is proposed for simulcast systems which use linear QAM (quadrature amplitude modulation) type modulation and the impact of the choice of tap weights on the energy efficiency, the system complexity, and the performance in the presence of a propagation delay difference between the signals of different base stations is demonstrated.
