Abstract: The present disclosure discloses a receiver device, including receiving antennas, radio frequency receivers, a configurable precision analog-to-digital converter, a switch device, a baseband processor, and an analog-to-digital controller. The switch device converts a first number of baseband analog signals into a second number of baseband analog signals. The configurable precision analog-to-digital converter converts the second number of baseband analog signals into a third number of first baseband digital signals. The configurable precision analog-to-digital converter combines at least two of first analog-to-digital converters into at least one second analog-to-digital converter so that the total number of the rest of the first analog-to-digital converters and the at least one second analog-to-digital converters is equal to the third number. The resolution of each of the second analog-to-digital converters is higher than the resolution of each of the first analog-to-digital converters.
