Embodiment Construction

[0015] Certain terms are used throughout the description and claims to refer to particular components. It should be understood by those skilled in the art that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0016] Please refer to figure 1 , figure 1 is a sc...

Abstract

The method involves receiving GNSS radio frequency signals. The GNSS radio frequency signals are converted into GNSS baseband signals using a radio frequency input processing unit (110). A measurement result is generated according to the GNSS baseband signals using a baseband processing unit (120). The calibration of the measurement result is performed using the predetermined inter channel bias. An independent claim is included for a GNSS receiver.

Description

[0001] 【cross reference】 [0002] This application claims the priority of US Provisional Application No. 61 / 566980, filed on December 5, 2011, the contents of which are incorporated in this application. 【Technical field】 [0003] The present invention relates to a global navigation satellite system (global navigation satellite system, referred to as GNSS) receiver, and more specifically, to an inter-channel bias correction (Inter-Channel bias calibration, referred to as ICB) method in a GNSS receiver and related devices. 【Background technique】 [0004] Currently, several GNSS systems have been developed and used commercially, such as the Global Positioning System (GPS) and the Global Orbiting Navigation Satellite System (GLONASS). Navigation satellites of the same or different GNSS can broadcast radio-frequency (radio-frequency, RF) signals for positioning in different frequency bands. For example, GPS navigation satellites broadcast RF signals in two frequency bands, name...
