  Automatic modulation recognition of digital signals is an essential for intelligent communication systems. Most automatic classifications of digital signal types deal with recognizing signals formats in presence of additive white Gaussian noise (AWGN) in channels. However, real world communication environments, such as wireless communication channels, suffer from fading effects. There are few methods proposed to perform in fading channels. This paper presents a high efficient method for identification of M-array phase shift keying (MPSK) digital signal type. The proposed method is heuristic hybrid, formed by a multilayer perceptron (MLP) neural network as the classifier and the bees algorithm (BA) as the optimizer. An equalizer is also used to reduce channel effects. A suitable combination of higher order statistics, up to eighth, is considered as prominent characteristics of signals. Simulation results validate the high efficiency of the proposed technique in recognizing the types of digital signals even at low SNRs. Manuscript profile

  Abstract In the worldview of mystical and ethical poets, image is one of the most effective strategies to express the transcendent mystical and moral concepts. Rumi, one of the most famous illustrators in the realm of mystical literature, while telling his stories and mystical and instructive and teachings in Masnavi M'anavi, has made the concepts tangible for his audience with his intelligent and artistic performance in using images. Amongst most of his poems, especially in Masnavi, nature and its phenomena have a special stance. One of the creatures that Rumi specifically illustrates and mentions in Masnavi is bee and its belongings (nectar, honey, wax and sting).Being aware of the importance of this insect in the Holy Qur'an and emphasizing on some of the most important aspects of its life, Rumi has established a link between this creature and some aspects of human life and used this insect to create real and virtual images of Masnavi to express mystical and moral concepts.Referring to Rumi's illustrations of bees in Masnavi by analyzing its imagery, this study tried to analyze the profound mystical and moral meanings and concepts hidden in these images and achieve knowledge and awareness of this creature and its images in Masnavi through their investigation and expansion.
