A Hybrid Antenna Element for Travelling Wave Dual-Plane Monopulse Slotted Waveguide Arrays
Gültepe, Gökhan; Doğan, Doğanay; Aydın Çivi, Hatice Özlem (2018-12-10)
A novel antenna element for low loss and low-profile dual-plane monopulse arrays is proposed. The travelling wave array has both sum and difference distributions in azimuth. The designed element is the unit cell of an interleaved slotted waveguide array feeding wideband printed antennas via probes inserted into waveguides from the slots. The use of printed antennas enhances the narrow sidelobe and efficiency bandwidth of the closely-spaced slotted waveguide arrays by up to 20%. The unit cells are modelled a...
A Low-Complexity Graph-Based LMMSE Receiver Designed for Colored Noise Induced by FTN-Signaling
Sen, Pinar; Aktas, Tugcan; Yılmaz, Ali Özgür (2014-04-09)
We propose a low complexity graph-based linear minimum mean square error (LMMSE) equalizer which considers both the intersymbol interference (ISI) and the effect of non-white noise inherent in Faster-than-Nyquist (FTN) signaling. In order to incorporate the statistics of noise signal into the factor graph over which the LMMSE algorithm is implemented, we suggest a method that models it as an autoregressive (AR) process. Furthermore, we develop a new mechanism for exchange of information between the proposed...
A Pattern Reconfigurable Compact Antenna Structure Based on Shorted Microstrip Patches
Çelik, Feza Turgay; Alatan, Lale; Aydın Çivi, Hatice Özlem (2022-01-01)
A compact pattern reconfigurable antenna structure is proposed. The proposed antenna structure is composed of two shorted quarter-wave microstrip patch antennas placed side by side to share a common shorting plane. Therefore, the total length of the antenna is a half wavelength. Pattern reconfiguration is achieved by exciting two antennas with different phases and consequently steering the main beam. With such a compact antenna, beam steering up to 350 is demonstrated.
A CDMA system wideband feedforward linearizer design based on an analytical model
Coskun, AH; Demir, Şimşek (2003-01-01)
Feedforward systems are complicated due to the presence of two nonlinear amplifiers and the requirement of amplitude, delay and phase match in two different loops. Analytical tools that characterize this complexity help the designer a lot in rapid and accurate initial optimizations, particularly for wideband applications. In this work we present a wideband feedforward linearizer design for CDMA applications, based on an analytical model and speed and accuracy aspects of the results are compared with RF simu...
