摘要
分析了基于3GPP标准对LTE系统射频接收机进行链路预算设计的方法。LTE系统射频接收机的链路预算设计是指通过对射频接收机的性能指标进行计算和预估,以确定系统所需的各个组成部分的参数和性能,从而确保射频接收机能够在特定的工作条件下正常运行。介绍了射频接收机链路预算的背景和意义,阐述了其在无线通信中的重要作用;从链路增益、噪声系数、阻塞、互调等方面详细介绍了接收机链路预算的设计方法。射频接收机的链路预算设计可以帮助工程师确定链路各个模块的指标要求,进一步确定各个模块内具体芯片的选型参数,从而快速完成链路设计。
The method of link budget design for LTE system radio frequency receivers based on 3GPP standards is analyzed.The link budget design of LTE system radio frequency receivers is defined as calculating and estimating the performance indicators of the radio frequency receiver to determine the parameters and performance of each component required by the system,so as to ensure the normal operation of the radio frequency receiver under specific working conditions.The background and significance of radio frequency receiver link budget are introduced,and its important role in wireless communication is expounded.The design method of receiver link budget is introduced in detail from aspects such as link gain,noise figure,blocking and intermodulation.The link budget design of radio frequency receiver can help engineers to determine the requirements of each module in the link,and further determine the selection parameters of specific chips within each module,so as to quickly complete the link design.
