    Channel Tracking Performance of Zero Tail Discrete Cosine Transform Spread OFDM Waveform
    (IEEE, 2018) Kavlak, Mukremin; Kus, Yasin; Elmagoz, Ugur; Özen, Ali
    In this paper, zero-tail discrete cosine transform spread OFDM (ZT DCT-S OFDM) waveform is proposed as an alternative to 5th generation (5G) waveform enhancement studies. In order to verify the performance of the proposed method and compare with the conventional OFDM and zero-tail discrete Fourier transform spread OFDM (ZT DFT-S OFDM) systems, computer simulations are performed on time invariant and time variant frequency selective Rayleigh fading channels. The obtained simulation results show that the proposed ZT DCT-S OFDM method has better bit error rate (BER) and channel tracking (carrier frequency offset, CFO) performance than conventional OFDM and ZT DFT-S OFDM systems.

    Zero tail unique word discrete sine transform spread OFDM
    (Institute of Electrical and Electronics Engineers Inc., 2018) Kus, Yasin; Kavlak, Mukremin; Elmagoz, Ugur; Özen, Ali
    In this paper, it is proposed a new unique word (UW) OFDM waveform based on zero-tail discrete Sine transform spread OFDM (ZT UW DST-S OFDM). The proposed waveform improves the ZT DST-S-OFDM and UW OFDM methods by removing the influence of the data symbols on the tail of the transmitted signal. In order to test the performance of the proposed method, computer simulation studies are performed on frequency selective Rayleigh fading channels. The obtained results confirm that the proposed waveform has better peak to average power ratio (PAPR) and bit error rate (BER) performance than the conventional OFDM, ZT DFT-S OFDM and ZT UW DFT-S OFDM systems. © 2018 IEEE.
