Low complexity peak-to-average power ratio reduction in OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ...
Index modulation-aided IQ imbalance compensator for OTFS communications systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Design of simple transceiver architectures is inevitable in order to provide low computational complexity, low power consumption and affordable cost in beyond 5G (B5G) wireless systems, but it results in hardware impairments ...
