In this article, we propose a new criterion for a switching algorithm to be used in MIMO‐OFDM systems. The switching algorithm, which selects between spatial multiplexing and MIMO diversity using the Demmel condition number as selection metrics, is first analyzed. Then, we show the limitation of this criterion, when increasing the receive antenna number. As a solution, we propose multiantenna processing...
In this paper we propose a low-complexity and high performance sum-of-sinusoid based architecture for the accurate simulation of Mobile-to-Mobile Rayleigh fading channels. Presented contributions concern the issues of designing and implementing a “double ring” Mobile-to-Mobile emulator, based on the Random Walk Process to reproduce accurately the behavior of the considered channel. Implementation...
A low-complexity and high performance configurable Double Rayleigh Mobile-to-Mobile fading channel emulator is proposed as well as its High Level Synthesis. The design and implementation of the proposed architecture based on a variant of the white Gaussian noise filtering method uses a minor hardware resource. The designed system is modeled using C/C++ high level language. Then the synthesis task...
This paper proposes a cascaded filter-based model that efficiently generates correlated complex Gaussian variates for mobile-to-mobile double-Rayleigh scattering multipath fading channels. We apply an infinite impulse response (IIR) filter followed by a variable interpolator, to accommodate different Doppler rates, can directly be applied to the design of so-called “double-Rayleigh” mobile-to-mobile...
This paper presents a new approach to design a Gaussian variate generator (GVG) circuit, based on the Box-Muller algorithm. The proposed GVG utilizes a double non-uniform segmentation combined with the use of CORDIC algorithm to reduce the block memory and to remove the hardware multipliers, respectively. These modifications result in a compact hardware which has a reduced resources occupation and...
