[matlab] Doppler DL : 0: A signal is transmitted using a carrier frequency of 900 MHz. It is transmitted through a multipath channel which can be modelled as Rayleigh fading. Assumingthe Dopper spread as 10Hz and the number of multipaths as 10, generate the Rayleigh faded signal. Compute the outage rate (the probability of the signal falls below certain rate, say ?10 dB) of the signal. Using MATLAB, demonstrate the path loss as a function of loss parameter for distances ranging from 2 km to 40 km. Calculate the power loss in dB

[matlab] Patch DL : 0: this code is to show how Matlab design works. I do not have the license of the code. This code can also be downloaded from files exchange. The structure includes of a single ground plane and it is consequently low cost and simple to fabricate. It is found that isolation of more than 40dB can be achieved between two parallel microstrip patch antennas with using of one pair of slit two walls in air between microstrip antennas, inter-antenna spacing (center to center) is 0.257lambda_0. Also we are investigated that with different shapes of EBG on the walls we can reduce S12 more than 4 dB. At 0.94GHz it is shown that this translates into a center to center separation between antennas of just 20 mm. Similarly the structure can be applied to reduce mutual coupling between three or four radiating elements. A simulation result is used to confirm the suppression of mutual coupling between closely-packed antenna elements.
