A novel waveform design based on discrete sine transform for 5G and beyond

Ali ÖZEN

n 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 this study, the effects of different UW sequences such as Zadoff-Chu, CAZAC, 15 bit PN, 8 bit complementary code keying (CCK), 0-word, 1-word and -1-word on the bit error rate (BER) and channel tracking (Doppler) performance of the proposed ZT UW DST-S OFDM systems are investigated. In order to test t ...Daha fazlası

Channel tracking performance of zero tail discrete cosine transform spread ofdm waveform

Ali ÖZEN

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 DCTS OFDM method has better bit error rate (BER) and channel tracking (carrier f ...Daha fazlası
