- 초록
- Massive MIMO technology is needed as the volume of data demand increases. An increase in the number of RF-chains as the number of antennas increases causes hardware complexity and system cost increase. This causes the application of the actual communication system to be delayed. In this paper, we show the applicability to massive mimo by expanding the unit load modulation module with single RF-chain type. 2× LM-MIMO to 4× LM-MIMO and showed N×N MIMO possibilities through actual 4× LM-MIMO implementation and 4× MIMO test.
