Dispersion Division Multiple Access Technique Based on Electromagnetic Time Reversal

The dispersion division multiple access technique based on electromagnetic time reversal (TR-DDMA) is analyzed and demonstrated using a model with a common channel and three dispersive microstrip lines. Three different messages are transmitted to a receiver simultaneously with the same carrier wave. By using the time reversal technique and three dispersive lines, the three messages can be independently output to three ports through a common channel, which demonstrates the effectiveness of the TR-DDMA technique.
