We derive here improved upper bounds on the error probability of block codes which are transmitted over fully interleaved Rician fading channels, coherently detected and maximum likelihood decoded. We assume that the fading coefficients during each symbol are statistically independent (due to a perfect channel interleaver), and that perfect estimates of these fading coefficients are provided to...

Asynchronous multiplexing schemes are efficient than synchronous schemes, in a bursty traffic environment of multiple access local area network (LAN), as fixed bandwidth is not allocated among the users and there is no access delay. FiberOptic Code-Division Multiple Access (FO-CDMA) is one such asynchronous multiplexing scheme suitable for high speed LAN networks. While FO-CDMA offers potential...

The ensemble performance of parallel and serial concatenated turbo codes is considered, where the ensemble is generated by a uniform choice of the interleaver and of the component codes taken from the set of time varying recursive systematic convolutional codes. Following the derivation of the input-output weight enumeration functions of the ensembles of random parallel and serial concatenated ...

Abstract The present study is meant to obtain tribological insight into the interface of a rolling rubber wheel on counter-surface disk based work previous Salehi et al. (Tribol Lett 68(1):37, 2020), in which new test method was developed rapidly predict tire grip laboratory environment. A Laboratory Abrasion Tester (LAT100) used and exploited as tribometer. This opened cost- time-effective hor...

Althaea officinalis (marsh mallow, Malvaceae) is a medicinal plant, the roots, leaves and flowers of which are usually used in traditional medicines many countries, including Iran (Kianitalaei et al., 2019). During survey April 2022, phytoplasma-type disease, tentatively named A. yellows (AOY), was observed patches plants naturally growing Golestan, near Shiraz (Fars province, Iran). In 2-ha su...

Background & Aims: Attachment styles result from a child’s early relationships with their primary care provider. We should bear in mind that there is a significant correlation between these styles and emotional disorders (death anxiety) occurring throughout an individual’s life. If these connections are not formed correctly during early childhood, the individual will most likely suffer mental a...
