Massive MIMO technology is considered to be an important technology in the future 5G. It is mainly used to improve the spectrum efficiency and power efficiency of the communication system. The advantage of massive MIMO and standardized process of MIMO were described and summarized in detail. The ...
intra-cluster interference can be eliminated. This concept has recently been introduced under a new network structure named CF massive MIMO [3]. It is considered a key enabling technology for 5G and beyond 5G wireless systems. Besides, the cell-edge problem inherent in cellular massive MIMO is ...
However, optimizing 5G network performance remains a challenging task, particularly in terms of Bit Error Rate (BER) and spectral efficiency. Multiple-Input Multiple-Output (MIMO) technology, coupled with beamforming algorithms, offers a promising solution to these challenges. This s...
对于5G AAU来说,由于广泛采用了M-MIMO技术,其内部集成的天线采用的振子数量更多,多个振子整整齐齐地排列着,严阵以待,因此也称作天线阵列。对于Sub6G频段的AAU来说,业界一般采用192个振子。 天线振子虽多,但单个振子的能力太过弱小,并且如果每个振子都和AAU内部的功放连接独立发送信号的话,实现上也过于复杂,因此业界...
