Channel capacity is usually undetermined in cooperative communication because of the various power allocations. In order to improve the channel capacity, power allocation for tri-terminal cooperative communication is discussed for Gaussian channel gains in EGC model and MRC model. The optimum power allocation algorithm, viewing channel capacity as the destination function, is presented. The pap...

—In this paper, we generalize the iterative algorithms proposed by Khandaker to amplify-and-forward multiuser Multiple-Input Multiple-Output (MIMO) relay communication systems with the source-destination links. Compared with the conventional algorithms, where the source-destination links are ignored, the evolved Tri-Step method and Bi-Step method are derived for the new system model with the s...

exchange rate pass-through to the price of traded goods is one of the important issues in economy of developing countries such as iran and affects the efficiency of the exchange rate policies to improve the trade balance. the main aim of this paper is to empirically analyze exchange rate pass-through to iran's saffron export price using panel data for twenty destination markets during 2000...

In this paper, we investigate an on-demand, link-state, multi-path QoS (quality-of-service) routing protocol in a MANET, which is important for many real-time multimedia applications. The basic idea of the on-demand, link-state, multi-path routing protocol is to reactively collect link-state information from source to destination in order to dynamically construct a partial network topology whic...

word of mouth (wom) is becoming increasingly recognized as an important form of promotion and an important source of information influencing consumer’s attitudes and purchase behavior, particularly within professional services environments, where credence qualities play a critical role in consumers’ choices. wom is especially important in tourism industry, whose intangible products are diff...

many countries have created systems for monitoring food products. however, these systems need paper and label and also, cannot find the origin and final destination of food product. radio frequency identification (rfid) has the capability of monitoring foods completely and track the mentioned points. this technology also can monitor many food products simultaneously. the usage of this system ca...

An Ad hoc network is a collection of mobile nodes forming a temporary network without the help of any centralized access point or existing infrastructure. In such an environment, routing protocols are required to transfer packets from source to destination as some mobile nodes can act as intermediate nodes to forward a packet to its destination, due to the limited range of each mobile node’s wi...

Market segmentation is an essential element of marketing in industrialized countries. Goods can no longer be produced and sold without considering customer needs and recognized the heterogeneity of these needs. In this paper, we use market segmentation approach in single product inventory system with deteriorating items. The objective is to make use of optimal control theory to solve the produc...
