Process in Week4

In the approach to the end of the project we have continued to make good progress, this week we have achieved the following: 1. The  Sustainability Report has been  submitted. 2.  The code for simulating the capacity performance of two channels is completed. The channel capacity of a flat fading channel with no dominant propagation along a line of sight can be expressed like this: Since the channel gain  has a Rayleigh distribution with pdf: T hen by the transformation theorem for single random variables: Then the channel capacity can be expressed like this: Using these equations, we can produce a figure of the maximum bandwidth efficiency that the signals can achieve in the flat Rayleigh fading channel as a function of the mean SNR during the transmission. The plot of the channel capacity per Hz of two channels is shown below: 3. T he figures that were obtained in previous weeks were analysed and a conclusion of the analysis was formed.   a). As the signal-to-n...

Process in Week3

 Week3 In week 3 we made some more good progress, here is an account of what we achieved: 1.  We made a good start on the Sustainability Report.  This report is due before we meet in week 4, the group intends on working on the rest of the report during the session for week 3. 2.  After discussing the issue as a group, we now collectively understood the concept of fading effect and the code for simulating the second noisy system is also completed. In our simulation, we assume that the bipolar NRZ signalling is transmitted through a long distance by tropospheric and ionospheric propagation with the effect of heavily built-up urban environment. We also assume that this is a flat fading channel and there is no dominant propagation along a line of sight. The channel power gain in this simulation is assumed to be independent of each other.  Therefore, the flat-fading channel has memoryless properties. The simplified transmission model is shown below: Figure 1: th...
