CMOS Front-End Circuits of Dual-Band GPS Receiver
A RF front-end chip for a dual-band Global Positioning System (GPS) receiver for L1 and L2 bands is designed using 0.25 μm CMOS technology. All function blocks of the GPS front-end are integrated onto one chip. The low noise amplifier has input matching over a wide frequency range to handle the L1 and L2 bands. This receiver uses a dualband image-reject mixer with the quadrature mixer sharing a...
متن کاملA Rapid Acquisition GPS receiver based on ultra tightly coupled IMU and GPS
Nowadays, the importance to obtain position in weak signal environments, such as indoors, has increased in order to take a step forward in the greater use of GPS. However, the weak signal environment may include several negative factors such as low signal to noise ratio, signal jamming and interference among others that shall be studied. The present thesis work proposes an open loop approach to...
متن کاملReceiver for Dual Band Applications
This dual-band CMOS receiver for GSM and DCS1800 applications incorporates hardware sharing between two paths to reduce the number of off-chip components [1]. The receiver is an extension of the Weaver single-sideband architecture [2]. Utilized in References 3 and 4, the Weaver architecture performs two consecutive quadrature downconversion operations on the signal and the image such that if th...
متن کاملFFT-Based Acquisition of GPS L2 Civilian CM and CL Signals
Block processing Fast Fourier Transform (FFT) algorithms have been developed to do signal acquisition for the new CM and CL civilian codes that will appear on the L2 GPS frequency once the Block IIR-M satellites are launched. These algorithms have been developed to aid in the acquisition of weak GPS signals. FFT block processing can be used to significantly reduce the computational burden cause...
متن کاملA Real-Time GPS Civilian L1/L2 Software Receiver
A dual-frequency civilian GPS receiver has been developed that runs 10 tracking channels in real time using a software correlator. This work is part of an effort to develop a flexible receiver that can use the new GPS L2C CM/CL signals as they become available on L2 without the need for new correlator hardware. The receiver consists of an RF front end, a system of shift registers, a digital dat...
