RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem
Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity. A Internet of Things (IoT) is network constituted by day-to-day objects equipped with some sensing system. These objects can also communicate with other objects for data exchange, wirelessly. This calls for a need of better wireless communication systems. New techniques using the 4G (Long-Term Evolution) have been developed to solve this problem, known as Advanced Antenna System (AAS).
