该论文提出了一种采用单路径数字中频架构的接收机,利用单个整数锁相环实现了5分量载波聚合(Inter/Intra 5-CA),解决了多载波接收机需要多个本振或复杂架构导致的功耗和面积问题。

However, as an effort to overcome the insufficient frequency-band resource in FR1, telecommunication companies are continuously securing additional re-farming bands in FR1, and they are extending maximum throughput by applying Carrier Aggregation/E-UTRA NR Dual connectivity (CA/EN-DC) based on many fragment bands as shown in Fig. 27.5.1. For example, a major telecommunication company supports CA/EN-DC of the B1, B3, B5, B7 (1), B7 (2), and n78 bands, which require more than 20 RX paths considering the antenna diversity and 4×4 MIMO needed for maximum throughput. As the demands for spectrum
