A compact, fast, and accurate realization of a digital Gaussian variate generator (GVG) based on the Box–Muller algorithm is presented. The proposed GVG has a faster Gaussian sample generation rate and higher tail accuracy with a lower hardware cost than published designs. The GVG design can be readily configured to achieve arbitrary tail accuracy (i.e.,(More)
An efficient implementation of Nakagami-m and Weibull variate generators on a single field-programmable gate array (FPGA) is presented. The hardware model first generates a correlated Rayleigh fading variate sequence and then transforms it into a sequence of Nakagami-m or Weibull fading variates. A biquad processor facilitates the compact implementation of(More)
Emulation of fading channels is a key step in the design and verification of wireless communication systems. Testing wireless transceivers with actual fading channels is inconvenient due to unrepeatable and uncontrollable channel conditions. In this paper we present a compact field-programmable gate array (FPGA) implementation for a circuit that generates(More)
We present an ultra-compact and fast hardware simulator for Rayleigh and Rician fading channels. To ensure numerical robustness and an efficient mapping onto hardware, the fading simulator uses the sum-of-sinusoids technique with N = 32 sinusoids added up to model each fading path. Fading samples are generated at a low rate and then are passed to an(More)
A stochastic sum-of-sinusoids based simulation model is proposed for Rayleigh and Rician fading channels. The time-averaged statistical properties of the new model have been significantly improved compared to existing models. Verification of the proposed fading simulator is carried out by comparing its measured statistical properties with the properties of(More)
We present a fading model with a compact and fast hardware implementation suitable for correlated Rayleigh fading channel simulators. The proposed scheme is based on the sumof-sinusoids model because of its flexibility and efficient mapping onto hardware. Using numerical simulation, it is shown that the statistical properties of the generated fading(More)
This article presents an ultra-compact and highthroughput reconfigurable architecture for implementing an efficient fading channel simulator that supports a relatively large number of propagation paths. To closely reflect actual radio signal propagation conditions, we used a recently improved Rayleigh and Ricean fading channel model based on the(More)
