In conventional orthogonal frequency division multiplexing with index modulation (OFDM-
IM), the-ary modulated symbols are transmitted on a subset of subcarriers under the …

In this paper, we propose a spatial modulation (SM) scheme referred to as complex
quadrature SM (CQSM). In contrast to quadrature SM (QSM), CQSM transmits two complex …

In this paper, we examine the robust beamforming design to tackle the energy efficiency
(EE) maximization problem in a 5G massive multiple-input multiple-output (MIMO)-non …

We present a precoding approach for spatial modulation (SM) for increased robustness
against spatial correlations over slow fading Rayleigh channels. This approach, based on …
