The industrial, scientific and medical band is widely used by different wireless systems. The identification of other wireless technologies in the common environment is one of the keys for correct system coexistence. In this work, a sensing platform for the detection of IEEE 802.11g and IEEE 802.15.4 primary signals in the 2.4 GHz band is proposed. The sensing platform makes use of a combined scheme...
a hybrid algorithm for primary user detection in spectrum sensing is proposed in this article, and its performance for different types of primary signals is evaluated and compared. The hybrid algorithm is a combination of the energy detection and the cyclostationarity-based methods. In the majority of related works, the input signal for the energy detection is modeled with a lognormal distribution...
We introduce the concept of stochastic degrees of freedom to semi-analytically approximate the distribution of nonlinear degree of polarization reduction values observed in numerical simulations as result of cross-polarization modulation.
We examine nonlinear fading in differential PSK receivers due to cross-phase modulation and determine its relevance in the presence of cross-phase modulation. We find that XPolM does not contribute to the nonlinear penalty.
