Özet
In this paper, extended fully improved quadrature space shift keying (EFIQSSK) modulation, which is a combination of extended quadrature spatial modulation (EQSM) scheme and fully improved quadrature space shift keying (FIQSSK), is proposed. EFIQSSK uses only antenna indices to modulate data bits, achieving a bit rate of four times the number of antennas per channel usage. The proposed scheme can be implemented with any number of antennas. It has a low complexity since it does not need any radio frequency (RF) chain on the transmitter side. In our study, the bit error rate performance of this technique is compared with the schemes in the literature with the same spectral efficiency. In addition, the transmission scheme used in the method has been optimized to provide low bit error. In the Monte Carlo simulations, it has been observed that the proposed scheme outperforms other schemes in the literature with the same spectral efficiency when using 3 or more transmit antennas.
