Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
Oğuz, Onur; Aygölü, Hasan Ümit; Panayırcı, Erdal (Wiley-Blackwell, 2008-01)In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ... -
Gezgin iletişim için uzay-zaman kodlamalı çok-taşıyıcılı tümleşik sistem tasarımı
Panayırcı, Erdal; Pusane, Ali Emre; Oğuz, Onur; Aygölü, Hasan Ümit (Tübitak, 2003-04)Günümüzde önemi hızla artan gezgin ve telsiz (mobile/wireless) iletişim sistemleri (uydu iletişimi, gezgin radyo, “indoor” iletişim) iletişim kanalının neden olduğu toplamsal Gauss gürültüsüne ek olarak sönümlemeden (fading) ... -
On the performance of trellis coded M-PSK systems over Rician fading channels with phase jitter
Uysal, Murat; Aygölü, Hasan Ümit; Panayırcı, Erdal (Assoc Elettrotecnica Ed Elettronica Italiana, 2001-02)In this paper, the performance of trellis coded M-PSK systems is investigated operating over Rician fading channels with phase jitter. Thus the results reflect not only the degradation due to the effect of fading on the ... -
Sequence estimation with transmit diversity for wireless communications
Panayırcı, Erdal; Aygölü, Hasan Ümit; Pusane, Ali Emre (Urban & Fischer Verlag, 2003)In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
