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:
Then by the transformation theorem for single random variables:
Then the channel capacity can be expressed like this:
e). Under the same signal-to-noise ratio, the error rate of the Rayleigh channel is much greater than that of the AWGN channel, and the attenuation of the Rayleigh channel is also slower.
f). When the bandwidth remains the same, as the signal-to-noise ratio increases, the capacity of both channels increases.
g). Under the same signal-to-noise ratio, the channel capacity of the Rayleigh channel is smaller than that of the AWGN channel. Therefore, under the same signal-to-noise ratio, the information transmission capability of the Rayleigh channel is weaker than that of the AWGN channel.
h). In the end, we can conclude that the AWGN channel is more effective and reliable than the Rayleigh channel.
4. We were then at a point where a poster could be created to display the data we had produced.
