介绍了一种利用UMTS和GNSS信号进行用户设备定位的混合接收机结构。在回顾了UMTS和Galileo/GPS信号结构以及接收机RF和基带架构的最新技术水平之后，提出了一种可配置的GNSS/UMTS架构。研究的概念是基于一个可重构的接收链，以防止重复的硬件，这将导致成本大大降低。Galileo接收机设计中的最大挑战是极其严格的噪声系数（NF）要求。集成GNSS/UMTS接收机的另一个关键问题是注入伽利略接收机的最大容许UMTS发射泄漏。
This paper introduces a hybrid receiver architecture for user equipment positioning by using UMTS and GNSS signals. After a review of the UMTS and Galileo/GPS signal structures and the state-of-the-art in receiver RF and base-band architectures, a configurable GNSS/UMTS architecture is proposed. The investigated concept is based on a reconfigurable receive chain to prevent duplication of hardware, which will result in considerably lower costs. The biggest challenge in the design of Galileo receivers are the extremely tight noise figure (NF) requirements. Another key issue of integrated GNSS/UMTS receivers is the maximum tolerable UMTS transmit leakage injected into the Galileo receiver.
