Abstract

The invention discloses a method for receiving a B1C QMBOC signal, a chip and a module, and aims to guide the B1C QMBOC signal through a B1I signal, reduce operation and storage resources required fordirectly capturing the B1C signal and reduce the power consumption of a receiver.

Description

technical field [0001] The present invention relates to the technical field of satellite navigation, more specifically, to the field of satellite navigation positioning signal processing. Background technique [0002] In recent years, with the development of wireless communication technology, the demand for mobile device navigation applications has surged, and the global satellite navigation system receiver has gradually developed towards system miniaturization, chip-based, and low power consumption. The realization of the acquisition function in the satellite navigation receiver depends on the super computing power of the receiver. Reasonably reducing the acquisition resources of the receiver is a more effective method to reduce the power consumption and chip cost of the receiver. The resources needed to capture long codes for satellite signals are significantly more than those required for short codes. For example, the long code signal (B1C) of BDS has a code length of 102...
