Channel estimation using radial basis function neural network in OFDM-IDMA system

Şimşir, Şakir; Taşpınar, Necmi (Springer, 2015)

In this paper, channel estimation based on Radial Basis Function Neural Network (RBFNN) is proposed to estimate channel frequency responses in orthogonal frequency division multiplexing–interleave division multiple access ...
Pilot tones design using Grey Wolf Optimizer for OFDM-IDMA system

Şimşir, Şakir; Taşpınar, Necmi (2017)

Since the channel estimation performance is affected directly by the positions of pilot tones, the optimization of pilot placement process known as having quite important role on minimizing the estimation errors has become ...
Pilot tones design using particle swarm optimization for OFDM-IDMA system

Taşpınar, Necmi; Şimşir, Şakir (2019)

Since the channel estimation performance is directly affected by the pilot positions, it has been a major task in multicarrier transmission schemes to adjust the pattern of pilot distribution for the purpose of minimizing ...
