A circularly symmetric multichannel audio recording and reproduction system has previously been proposed by Johnston and Lam [1]. This system aimed at perceptual reconstruction of the sound field and employed a sparse circular array of directional microphones driving a matching array of loudspeakers. An improvement to that system based on stereophonic time-intensity panning concepts has recently been proposed [2]. In this paper localisation performance of that system is compared with the original Johnston/Lam configuration, and 2nd-order Ambisonics using a formal subjective localisation test. It is found that, for a listener positioned at the centre of the multichannel reproduction system, the newly proposed improvement to Johnston/Lam system delivers a more accurate spatial rendition of the sound sources as compared to the 2nd-order Ambisonics decoder we used.

Perceptual Soundfield Reconstruction in Three Dimensions via Sound Field Extrapolation
Erdem, Ege; De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2019-05-01)
Perceptual sound field reconstruction (PSR) is a spatial audio recording and reproduction method based on the application of stereophonic panning laws in microphone array design. PSR allows rendering a perceptually veridical and stable auditory perspective in the horizontal plane of the listener, and involves recording using nearcoincident microphone arrays. This paper extends the PSR concept to three dimensions using sound field extrapolation carried out in the spherical-harmonic domain. Sound field render...
A Comparison of spatial modulation and spatial multiplexing systems in multipath fading channels
Saygılı, Halil; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2013)
In this thesis, multiple antenna transmission techniques like spatial multiplexing, spatial modulation and multiple active spatial modulation are compared in multipath fading channels. Maximum likelihood sequence estimation (MLSE) based on the Ungerboeck observation model is the optimal operation for intersymbol interference channels and applied on the mentioned multiple antenna transmission strategies. The performance analysis based on Monte Carlo simulations and comparison of the computational complexity ...
The Effect of Antenna Correlation in Single-Carrier Massive MIMO Transmission
Beigiparast, Nader; Güvensen, Gökhan Muzaffer; Ayanoglu, Ender (2018-07-20)
This work presents a single-carrier massive MIMO transmission system for the frequency selective Gaussian multi-user channel. It considers both cases of spatially uncorrelated and correlated channel and compares them in terms of the user sum-rate as well as the general performance. We consider a channel with M antennas at the base station which provides services for K single-antenna users. We develop a general expression for the achievable rate among users in the channel with a correlation among antennas at...
Modelling sound source localization under precedence effect using multivariate Gaussian mixtures
Hacıhabiboğlu, Hüseyin (2002-10-10)
The precedence effect refers to the property of the human auditory system that enables accurate localization of sound sources where many interfering echoes of the original signal are also present. Perception of the elevation, azimuth, and distance of sound sources are affected in the presence of an echo. The multivariate Gaussian mixture model proposed in this paper combines azimuth, elevation and distance perception, and provides a general framework for mode...
Implementation of a digital signal synthesizer with high spurious free dynamic range
Kılıç, Argun; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2006)
Today’s analog modulators and upconverters are inadequate to synthesize and modulate signals with high ‘Spurious Free Dynamic Range’ (SFDR). Thus, the main objective of this thesis is to design and implement a ‘Digital Signal Synthesizer’ (DSS) that is capable of synthesizing signals between 50-100 MHz with 60dB SFDR and to modulate them variable symbol rates and modulation techniques with very high phase/frequency resolution and switching speed while keeping the amplitude modulation occurring during a modu...
