A quasi-cyclic (QC) low-density parity-check (LDPC) code is called type-II, if the maximum weight over all circulants appearing in the parity-check matrix has the value of two. On the basis of multiplicative subgroup analysis for the prime field, a n

The greatest-common-divisor (GCD) method is a general framework employing a set of simple inequalities (called GCD constraint) to guarantee girth eight for a class of $(J,L)$ quasi-cyclic (QC) low-density parity-check (LDPC) codes. However, an import

Filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) has been studied as an alternative waveform for post-orthogonal frequency division multiplexing (OFDM) wireless communications. However, due to the intrinsic imaginary i

Because of the intrinsic imaginary interference in filter bank multicarrier employing offset quadrature amplitude modulation (FBMC/OQAM) systems, accurate channel estimation remains an open issue, which will be studied in this letter. By using the re

Cooperative spectrum sensing has been shown to be an effective approach to improve the detection performance by exploiting the spatial diversity among multiple cognitive nodes. By using the amplify-and-forward relaying with partial relay selection, t

In this study, the authors present a cooperative spectrum sensing scheme based on opportunistic amplify-and-forward relaying (denoted by CSS-OAFR), which provides higher detection performance by selecting the best cognitive relay and is interesting i
