Background:
A new wireless multiple access technology enabled by using Time Modulated
Arrays (TMAs) is proposed in this paper.
Methods:
It benefits due to the requirement of only a single Radio Frequency (RF) chain, compared
with other multiple-RF-chain schemes.
Results:
As a result, it is able to greatly reduce the system cost, energy consumption, and complexity.
Conclusion:
In addition, the signal through the single RF chain is narrow-band modulated, reducing the
signal Peak-to-Average-Power-Ratio (PAPR), thus, further enhancing the power efficiency of the RF
chain, especially for power amplifiers. The operation principle and synthesis approach are elaborated in
this paper, and are demonstrated with two examples.
