Large Scale Fading and Channel modeling Using Matlab March 2012 Large scale fading and channel modeling Using Matlab Introduction The fading phenomenon can be broadly classified into two different types: large-scale fading and small-scale fading. Large-scale fading occurs as the mobile moves through a large distance‚ for example‚ a distance of the order of cell size . It is caused by path loss of signal as a function of distance and shadowing by large objects such as

how well a material conducts electricity. According to physics from the University Of Maryland‚ graphene can reach a carrier mobility of up to 200‚ 000 cm2/V-1s-1 at room temperature6. As opposed to intrinsic silicon with a carrier mobility of 1500 cm2/V-1s-1‚ we can see that graphene is not only better but it overpasses silicon’s carrier mobility by 133 times11. It is clear that graphene can be a good candidate to replace silicon in the electronics industry. For example‚ Intel Corporation now sells

In this report I will explain how and why laboratory and industrial scale differ using the example of preparation of aspirin. The first difference is that instead of weighing the 2-hydroxybenzoic acid on scales on a work bench in a beaker as you would in small scale‚ it is easier and safer to weigh it onto scales‚ in a plastic bag on the floor. This is easier
