Performance analysis of generalized orthogonal code index modulation system

open access: yesDianxin kexue, 2022
In order to improve the transmission efficiency of the code index modulation (CIM) system, a generalized orthogonal code index modulation (GQCIM) system with lower complexity was proposed, which was a single input single output (SISO) system.CIM system ...

Enhanced spatial modulation with generalized antenna selection in MISO channels

open access: yesIET Communications, 2021
Here, an enhanced spatial modulation with generalized antenna selection (ESM‐GAS) for multiple‐input single‐output systems is proposed. Unlike the conventional SM systems, in ESM‐GAS, the number of active antennas is not fixed, but varies from only one ...
