The performance of a low-complexity detection technique for OFDM-IM over the Nakagami-m fading channel has been analyzed. The orthogonal frequency-division multiplexing with index modulation (OFDM-IM) has recently been used in conjunction with the subcarriers using on-off keying modulation. The result shows improved performance in comparison with the(More)
 This paper presents the theoretical analysis for Noncoherent multi-tone code division multiple access (MT-CDMA) system in terms of average bit error rate (BER). The system uses differential binary phase shift keying (DBPSK) modulation and post-detection diversity combining, considering slowly Rician fading and frequency selective channel in the indoor(More)
Recently, Orthogonal Frequency Division Multiplexing with Index Modulation (OFDM-IM) has been introduced as a novel multi-carrier system to carry additional information bits compared to conventional OFDM. In this paper, we provide a closed-form expression of an OFDM-IM system for M-ary signal constellations such as M - QAM and M - PSK modulation schemes(More)
