In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
Food security is threatened by the combined pressures of increasing populations and climate change. Agricultural land vulnerable to overexploitation environmental Within this review, we identify role multiple cropping systems as an adaptation method towards Intercropping, relay or simultaneous cultivation two more crops, agroforestry, incorporation trees on at least 10% agricultural land, provi...
Relay cropping is a method that increases total productivity through maximum utilization of resources. In this study, we planned field experiment, which was conducted at the Regional Agricultural Research Station, Ishwardi, Pabna during 2016-2017 and 2017-2018 to find out most suitable way relaying mukhikachu (MU) with hybrid maize get benefit. Seven treatments: T1= silking stage (100 DAS), T2 ...
Weed competition is a significant problem in maize (Zea mays, L.) production in Sub-Saharan Africa. Better understanding of weed management and costs in maize intercropped with beans (Phaseolus vulgaris, L.) during transition to conservation agricultural systems is needed. Changes in weed population and maize growth were assessed for a period of three years at Bungoma where crops are grown twic...
In this paper, power efficiency (PE) of a relay interference channel including multiple transmitter nodes, multiple relay nodes and multiple destination is investigated. It is assumed that the destination and transmitter nodes are equipped with a few number of antennas but the relay nodes have a large number of antennas. Amplify-forward and decode-forward schemes by using MRT/MRC and ZF process...
Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...
Relay intercropping systems with rice cultivars (WAB450-24-3-2-P18-HB (V4) and WAB56-50), the competitive Cajanus cajan and the weakly competitive Stylosanthes hamata were evaluated in the tropical savanna zone in Côte d’Ivoire. The INTERCOM model for competition served for data analysis and understanding of the system based on phenological, physiological and morphological characteristics of th...
