| Zusammenfassung: | The present invention relates to a method for deriving a lower limit of a channel capacity in a terahertz MIMO system with a 1-bit transceiver and a system thereof. The method comprises the following steps of: deriving a lower limit of a channel capacity by utilizing a discrete fourier transform (DFT)-based eigenspace analog precoder and a combiner provided by an line-of-sight (LOS) MIMO channel configured by uniform circular arrays (UCA) on both sides; and suggesting an optimal power allocation method through the derived lower limit of the channel capacity.
