An efficient technique based on firefly algorithm for pilot design process in OFDM-IDMA systems

Taşpınar, Necmi; Şimşir, Şakir (2018)

Accurate placement of pilot tones has been a crucial task in multicarrier transmission technologies since there is a strong relation between pilot positions and channel estimation performance. Therefore, the firefly algorithm ...
Bio-inspired pilot design approach based on genetic algorithm for OFDM-IDMA scheme

Taşpınar, Necmi; Şimşir, Şakir (2020)

It is well known that the efficiency of a channel estimator employing the strategy of comb-type pilot placement can be controlled by adjusting the positions of pilot tones. In this paper, by considering this situation, in ...
Channel estimation techniques in OFDM-IDMA systems

Taşpınar, Necmi; Şimşir, Şakir (2014)

In this paper, pilot based channel estimation techniques for orthogonal frequency division multiplexing-interleave division multiple access (OFDM-IDMA) systems are investigated. Least Squares (LS) and Minimum Mean Square ...
Channel estimation using neural network in Orthogonal Frequency Division Multiplexing-Interleave Division Multiple Access (OFDM-IDMA) system

Şimşir, Şakir; Taşpınar, Necmi (2014)

In this paper, channel estimation based on neural network trained by Levenberg-Marquardt Algorithm is proposed to estimate the channel coefficients in Orthogonal Frequency Division Multiplexing-Interleave Division Multiple ...
