CDMA:

  • It is known as “Code-Division Multiple Access”.
  • Many radio communication technologies use the CDMA.
  • It is an example of multiple accesses, where many transmitters can send data concurrently in a single communication channel.
  • It belongs to the family of channel partitioning protocols and it also prevent in WLAN and cellular technologies.

Your challenge is to use MATLAB to plot a received signal at a base station in a multipath channel when the transmitter sends a sinusoidal carrier signal. A transmitter sends a sinusoidal signal of frequency 1.5 MHz to the base station. There is a line-of-sight (LoS) path to the base station receiver, with delay 1 usec. The signal on this path is attenuated in amplitude by a factor 0.9 (the LoS amplitude gain). There are also three single bounce paths, one of delay 2 usec, with an amplitude gain of 0.5, one of delay 7 usec, with an amplitude gain of 0.4, and a third of delay 10 usec, with amplitude gain of 0.2. These parameters are fixed and do not change during the transmission. The project is to write MATLAB code to obtain the signal received at the receiver. Plot the signal over a time interval of 20 usec, including axes, and provide units for the time axis. Then answer the following questions: a) How is the output signal frequency related to the input signal frequency? b) Does the…
Exhibit and explain the FSM representation of the sender side for a channel with bit errors in the following manner:
Q2. A signal travels from point A to point B through a link. It was found that at point B, the signal's power was 65W, whereas, at point A it was 98 W. Explain why there is a difference in the signal strength. What is the difference in the strength between these 2 points in decibels? Show your calculation and explain what does your result state
