Problems solved by technology

For example, traditional GNSS receivers will separately collect GPS signals in the first layer (Layer1) frequency band and GLONASS signals in the first layer frequency band. Successfully collected GPS and GLONASS data
Since the traditional GNSS receiver has only one set of receiving circuits that cannot receive GPS and GLONASS data at the same time, one of the methods to solve this problem is to set two sets of GNSS receiving circuits in the GNSS receiver. However, using two sets of The receiving circuit will increase the cost of the circuit and the size of the circuit

Embodiment Construction

[0019] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in names as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification 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 a first device is coupled to a 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. .

[0020] like figure 1 as shown, figure 1 It is a b...

Abstract

A receiver of a GNSS system is provided. The receiver comprises two mixers and a processing circuit. The first mixer down-converts an input radio-frequency signal comprising a first GNSS signal and a second GNSS signal into a first low-frequency signal. The second mixer down-converts the input radio-frequency signal into a second low-frequency signal. The processing circuit generates at least one phase-shifted low-frequency signal according to at least the first low-frequency signal, extract signal components of the first GNSS signal by rejecting signal components of the second GNSS signal according to the second low-frequency signal and the at least one phase-shifted low-frequency signal, and extract signal components of the second GNSS signal by rejecting signal components of the first GNSS signal according to the second low-frequency signal and the at least one phase-shifted low-frequency signal. The first and second GNSS signals are situated in different frequency ranges.

Description

technical field [0001] The present invention relates to a receiving mechanism, in particular to a front-end circuit arranged in a receiver to collect signals of various communication systems and a method for receiving related communication signals. Background technique [0002] Traditional global navigation satellite system (GNSS) receivers can support multiple GNSS services, such as global positioning system (GPS) and GLONASS, but for such GNSS receivers However, it is impossible to receive / collect multiple GNSS signals at the same time. For example, traditional GNSS receivers will separately collect GPS signals in the first layer (Layer1) frequency band and GLONASS signals in the first layer frequency band. Successfully collected GPS and GLONASS data. Since the traditional GNSS receiver has only one set of receiving circuits that cannot receive GPS and GLONASS data at the same time, one of the methods to solve this problem is to set two sets of GNSS receiving circuits in...
