“…In [5], the power allocation has been discussed for a multi-node network but decode-and-forward (DF) relaying protocol has been employed over Rician fading channel. Moreover in [6] [7] and [8], OPA has been derived for AF dual-hop network with arbitrary number of relays over Rayleigh fading. In this paper OPA has been derived for AF multi-hop network with multiple relays using moment generation function (MGF) method.…”

Abstract-Cooperative transmission is one of the promising techniques in wireless communication systems that enables the cooperating node in a wireless sensor network to share their radio resources by employing a distributed transmission and processing operation. This technique offers significant diversity gains as several cooperating nodes forward source node's data to the destination node over independently fading channels. The benefits offered by cooperative transmission can only be exploited fully if the power is allocated between source and cooperating nodes in an optimal manner instead of equal power allocation (EPA). Therefore, in this paper using moment generating function (MGF) approach a closed-form expression of probability of error has been derived for multi-hop cooperative network employing amplify-and-forward (AF) over rayleigh fading channel. Moreover, using two different network scenarios, optimal power allocation (OPA) scheme has been further investigated on the basis of channel link qualities between the communicating nodes. Numerical and simulation results validate the performance improvement of OPA over EPA and further the improvement due to relay location in the cooperative network.

Abstract-Music genre classification is a vital component for the music information retrieval system. There are two important components to be considered for better genre classification, which are audio feature extraction and classifier. This paper incorporates two different kinds of features for genre classification, timbral texture and rhythmic content features. Timbral texture contains the Mel-frequency Cepstral Coefficient (MFCC) with other several spectral features. Before choosing a timbral feature we explore which feature contributes a less significant role on genre discrimination. This facilitates the reduction of feature dimension. For the timbral features up to the 4-th order central moments and the covariance components of mutual features are considered to improve the overall classification result. For the rhythmic content the features extracted from beat histogram are selected. In the paper Extreme Learning Machine (ELM) with bagging is used as the classifier for classifying the genres. Based on the proposed feature sets and classifier, experiments are performed with two well-known datasets: GTZAN and the ISMIR2004 databases with ten and six different music genres, respectively. The proposed method acquires better and competitive classification accuracy compared to the existing approaches for both data sets.
