In this paper, a new schematic of quadrature index modulation (QIM) with generalized spatial constellations is proposed and amalgamated with the media-based modulation (MBM) system for not only achieving the transmit diversity gains but also increasi

In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branc

With the rapid development of the underwater Internet of Things (IoT), the number of underwater communication nodes is rapidly increasing. The access capacity of a traditional multi-antenna communication system is limited by the number of transmittin

In this paper, in pursuit of enhancing the spectral efficiency and reliability of transmission in multiple-input multiple-output (MIMO) communication system, a new design method, named as the generalization of quadrature index modulation (GQIM), is p

In the paper, we proposed a method of space-time diversity on the transmitting side, combining a closed feedback and quasi-orthogonal space-time coding technique called closed-loop control with quasi-orthogonal space-time block coding (QO-STBC). For

Double spatial modulation (DSM) is a transmission technique which has been recently proposed for multiple-input multiple-output (MIMO) communication systems. DSM has a higher spectral efficiency compared with classical spatial modulation (SM), as it

With the increase in the complexity of communication systems, order statistics have become increasingly significant in performance evaluation, especially for advanced diversity techniques over fading channels. However, existing analytical approaches
