Discussion Overview

The discussion centers on simulating Orthogonal Frequency Division Multiplexing (OFDM) using 16-bit Quadrature Amplitude Modulation (QAM) in MATLAB's Simulink environment. Participants address challenges related to generating digital signals and splitting them into multiple data streams, which are essential for OFDM implementation.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • The original poster expresses difficulty in simulating digital signals for OFDM after successfully simulating analog signals.
  • Some participants suggest that the topic may be better suited for the Electrical Engineering or Computer Science forums for more targeted assistance.
  • The original poster later shares a potential solution involving a Random Integer Generator followed by an Integer to Bit Converter for generating digital signals.
  • The original poster raises a new question regarding the role of the "Conjugate function" in the "Math functions" block within the context of communication simulation.

Areas of Agreement / Disagreement

The discussion remains unresolved regarding the best approach to simulate digital signals for OFDM, as participants have not reached a consensus on the effectiveness of the proposed solutions or the role of the "Conjugate function."

Contextual Notes

Participants have not provided detailed results of their simulations, and there may be missing assumptions regarding the specific configurations used in MATLAB. The discussion also reflects varying levels of familiarity with the tools and concepts involved.

Homework Statement


I want to simulate OFDM using 16-bit QAM in Simulink. The main problem that I'm facing is regarding generation of digital signals and splitting a digital signal into two or more data streams, as we require in OFDM.



Homework Equations





The Attempt at a Solution


I have tried my bit. I have been able to simulate Analog signals, but digital signals are proving problematic for me.

Welcome to PhysicsForums!

Unfortunately, I can't help you with your main posting (I've also reported it to the Mods in the hope that it might be moved to the actual EE or CS forum, where it may find a wider audience). As far as the poll question goes, I think it's rather subjective: are we talking types of devices, different communications modes, maximum linked devices utilizing a certain communications scheme, etc.?

Thread moved to EE for now.

Welcome to the PF therash09. Can you show us the results of the simulations that you've done so far?
 
How can I show the results to you?

I have been able to simulate Analog Signals in MATLAB.
But Digital signals proved problematic for me.
However now I have got the technique.

The solution is:
Random Integer Generator, followed by Integer to Bit Converter.
Thankyou all who replied.


Now I have a new doubt. What is the role of "Conjugate function" in "Math functions" block in Communication simulation?

Rest, I'll keep trying and get back wth new doubts, if any!
