A year two project by group 136. We will look into the basic concepts of how wireless communication (3G in particular) is transmitted securely and discretely by using methods such as modulation with pseudo code to transform the signal basically into 'random' noise.

Walsh code spreading
The figure to the left shows how the Walsh code is multiplied with the data to give a spread signal with a higher frequency. The Walsh code and the data were both created using Matlab along with the plotted graphs.
