Article Citation - WoS: 3Citation - Scopus: 3Hardware Realization of a Low-Complexity Fading Filter for Multipath Rayleigh Fading Simulator(Springer Verlag, 2011) Özen, Serdar; Arsal, Ali; Toker, Kadir AtillaA low-complexity high performance Rayleigh fading simulator, and its Field Programmable Gate Array (FPGA) implementation are presented. This proposed method is a variant of the method of filtering of the white Gaussian noise where the filter design is accomplished in the analog domain and transferred into digital domain. The proposed model is compared with improved Jakes' model, auto-regressive (AR) filtering, existing auto-regressive moving-average (ARMA) filtering techniques, and inverse discrete Fourier transform (IDFT)-based techniques, in performance and computational complexity. The proposed method outperforms AR(20) filter and modified Jakes' generators in performance. Although IDFT method achieves the best performance, it brings a significant cost in storage. The proposed method achieves high performance with the lowest complexity, and its performance has been verified on commercially available FPGA platforms. Our fixed-point Rayleigh fading-channel emulator uses only 2% of the configurable slices, 1% of the Look-Up-Table (LUT) resources and 3% of the dedicated multipliers on the FPGA platform that has been used.Conference Object Citation - Scopus: 1Fpga Implementation of a Low-Complexity Fading Filter for Multipath Rayleigh Fading Simulator(Institute of Electrical and Electronics Engineers Inc., 2011) Toker, Kadir Atilla; Özen, Serdar; Arsal, AliA low-complexity high performance Rayleigh fading simulator and its Field Programmable Gate Array (FPGA) implementation are presented.

This proposed method is a variant of the method of filtering of the white Gaussian noise where the filter design is accomplished in the analog domain and transferred into digital domain. The proposed model is compared with improved Jakes' model, autoregressive filtering and IDFT techniques, in performance and computational complexity. Proposed method outperforms AR(20) filter and modified Jakes' generators in performance. Although IDFT method achieves the best performance, it brings a significant cost in storage and is undesirable. The proposed method achieves high performance with the lowest complexity.
