Use of 1-bit analog-to-digital converters in massive multiple-input multiple-output (MIMO) systems has been investigated widely due to the very low power consumption and implementation complexity they have. In this study, we present the benefits of temporal oversampling at the receiver side in 1-bit quantized uplink wideband massive MIMO systems. By expressing the oversampled system in a simple form, we derive the zero-forcing (ZF) detector. With ZF detector, oversampling provides up to 9 dB SNR gain in terms of symbol error rate compared to symbol rate sampling case. We also make the error rate analysis of such systems. Moreover, we show that the necessary number of antennas at the receiver side can be reduced significantly with temporal oversampling.

A Monolithic Phased Array with RF MEMS Technology
Sağkol, Hüseyin; Topallı, Kaan; Ünlü, Mehmet; Aydın Çivi, Hatice Özlem; Koç, Seyit Sencer; Demir, Şimşek; Akın, Tayfun (2002-08-07)
This paper reports a monolithic phased array implemented using RF MEMS technology. The phased array is composed of a linear array of four patch antennas and a new phase shifter design, monolithically integrated into a glass substrate. The new phase shifter design consists of two sections: one continuous and one discrete phase shifter. Combination of these two types makes it possible to give continuous and large phase shifts at the same time. The phase shifter can provide a phase shift of about 95/spl deg/ c...
Oversampling in One-Bit Quantized Massive MIMO Systems and Performance Analysis
Üçüncü, Ali Bulut; Yılmaz, Ali Özgür (2018-12-01)
Low-resolution analog-to-digital converters (ADCs) have attracted much attention lately for massive multiple-input multiple-output (MIMO) communication and systems with large bandwidth. Especially, 1-bit ADCs are suitable for such systems due to their low-power consumption and cast. In this paper, we illustrate the benefits of using faster than symbol rate (FTSR) sampling in an uplink massive MIMO system with 1-bit ADCs in terms of symbol error rate (SER). We show that the FTSR sampling provides about 5-dB ...
Modified neural multiple source tracking algorithm in the presence of mutual coupling
Caylar, Selcuk; Leblebicioğlu, Mehmet Kemal; Dural, Guelbin (2007-06-15)
In smart antenna systems, mutual coupling between elements can significantly degrade the processing algorithms [1]. In this paper mutual coupling effects on Modified Neural Multiple Source Tracking Algorithm (MN-MUST) has been studied. MN-MUST algorithm applied to the Uniform Circular Array (UCA) geometry for the first time. The validity of MN-MUST algorithm in the presence of mutual coupling has been proved for both Uniform Linear Array (ULA) and UCA. Simulation results of MN-MUST algorithm are provided fo...
Design of series-fed printed slot antenna arrays excited by microstrip lines
İncebacak, Mustafa; Alatan, Lale; Department of Electrical and Electronics Engineering (2010)
Series-fed printed slot antenna arrays excited by microstrip lines are low profile, easy to manufacture, low cost structures that found use in applications that doesn’t require high power levels with having advantage of easy integration with microwave front-end circuitry. In this thesis, design and analysis of microstrip line fed slot antenna arrays are investigated. First an equivalent circuit model that ignores mutual coupling effects between slots is studied. A 6-element array is designed by using this e...
Asynchronous design of systolic array architectures in cmos
İsmailoğlu, Ayşe Neslin; Aşkar, Murat; Department of Electrical and Electronics Engineering (2008)
In this study, delay-insensitive asynchronous circuit design style has been adopted to systolic array architectures to exploit the benefits of both techniques for improved throughput. A delay-insensitivity verification analysis method employing symbolic delays is proposed for bit-level pipelined asynchronous circuits. The proposed verification method allows datadependent early output evaluation to co-exist with robust delay-insensitive circuit behavior in pipelined architectures such as systolic arrays. Reg...
