    Single carrier frequency domain equalizer with unique word prefix
    (Institute of Electrical and Electronics Engineers Inc., 2018) Elmagöz, Ugür; Kuş, Yasin; Kavlak, Mükremin; Özen, Ali
    In this paper, a novel single carrier frequency domain channel equalizer (UW SC-FDE) is proposed, which uses different unique word (UW) sequences instead of the cyclic prefix (CP). The effects of CAZAC, Zadoff-Chu, PN, 0-word, 1-word and -1-word sequences on the performance of the proposed method are investigated. In order to evaluate the performance of the proposed method, simulation studies have been done on frequency selective Rayleigh fading channels. The obtained simulation results illustrate that the proposed UW SC-FDE technique has better bit error rate (BER) and peak to average power ratio (PAPR) performances than the conventional SC-FDE and conventional OFDM-FDE methods. © 2018 IEEE.
