This article proposes a hardware triply selective Rayleigh fading channel emulator which is implemented by incorporating spatial and inter-tap correlation matrices into uncorrelated frequency-flat Rayleigh fading waveforms with a Kronecker product method. The Kronecker product of square roots of three correlation matrices are computed in real time via serial, parallel, or mixed serial-parallel computational...
Abstract-Given the ever growing demand for radio spectrum,cognitive radio has recently emerged as an attractive wireless technology. Since orthogonal frequency division multiplexing (OFDM) is one of the major wideband transmission techniques, detection of OFDM signals in low signal-to-noise-ratio (SNR)scenario is an important research problem. In this paper, it is shown that the cyclic prefix correlation...
