LAB:CDMA Simulation Using MATLAB
This program models a simple implementation of CDMA technology. It considers 20 bit data streams sent by 3 senders across a common channel. Each sender uses a unique code word, given by the Walsh set, to encode its data, send it across the channel, and then perfectly reconstruct the data at 3 receivers.
The simulation utilizes these simplifications:
1. The individual data streams share the same bit length.
2. The code words are determined using the Walsh set to create orthogonal code words.
3. The “spreading factor” M of each code word is identical.
4. All users (data streams and codes) are synchronized in time.
5. Set-up and hold times of real-world systems are ignored.
6. The channel through which the data passes is ideal.
I- Use the Matlab script provided as m-File.
II- Record the results, 2 passes.
III- First pass Second pass
