Time division multiplexing for analogue signal

Click For Summary
SUMMARY

The discussion focuses on implementing Time Division Multiplexing (TDM) for an upconverted 1 GHz signal in an Orthogonal Frequency Division Multiplexing (OFDM) system. Participants clarify that while TDM can be applied, it may not be scientifically optimal as it creates a new spectrum for GSM or any TDM system. The conversation also touches on using MATLAB for this purpose, specifically recommending the use of a carrier signal multiplied with modulated data using Gaussian Minimum Shift Keying (GMSK), although GMSK is primarily for digital modulation. The feasibility of using Frequency Division Multiplexing (FDM) for signals at 1 GHz and 1.2 GHz is also questioned.

Hi guys, I am designing an OFDM system and then upconverted at 1 GHz. Now I have an idea of implementing TDM for this 1 GHz signal.

Is it possible, please explain from theoretical point of view and if possible, please help from MATLAB perspective.

Thank you very much,

i think that if you mean by TDM gsm system "for example" then its easy.
but not good from science point of view as you have just created new spectrum for gsm or ay TDM system.
any way in MATLAB use acarrier and multiply it with your modulated data by GMSK.
good luck
 
Hi there, thanks for your reply. But GMSK is for digital modulation. After upconverting my signal to 1 GHz, it will be analogue then.

For an instance, say I have a signal with carrier frequency of 1 GHz and 1.2 GHz, can I use FDM to multiplex them?

Thank you!
