1.3MBRAR

Version: matlab2021a, includes simulation operation video, operation video is played using windows media player.

Content: multipath channel BER matlab simulation, comparing ideal channel, normal additive Gaussian white noise channel and multipath channel. Simulation parameters:

N=2^10; % number of sampling points

L=64; % number of samples per code element

M=N/L; % number of code elements

Rb=2; % code rate is 2Mb/s , code rate unit is Mb/s

Ts=1/Rb; % code element spacing

dt=Ts/L; % time-domain sampling interval , time in microseconds

df=1/(N*dt) % frequency domain sampling interval ,frequency unit is MHz

T=N*dt; % short cutoff time

Bs=N*df/2; % system bandwidth

Na=4; % oscilloscope scan width is 4 code elements

Discuss the distribution of light intensity and interference fringes when two beams of monochromatic light of the same frequency meet at a point in space.

Note: Note that the current folder path on the left side of MATLAB, must be the location of the program folder, you can refer to the video recording.
