一种提升LTE分集接收灵敏度的设计方案

A Design for Increasing the Receiving Sensitivity of LTE Diversity

基于LTE设备的广泛使用和用户需求的增长,提出了一种提升LTE分集接收灵敏度的方案,通过使用极低噪声系数、较高增益的放大器并采用两级级联的方式,降低了整机的噪声系数,从而提升了接收机的灵敏度。对接收机的理论分析和测试对比表明,该方案具有结构简单、高指标等特点,可以推广到各种无线接收机产品中,具有广泛的应用前景。

Based on the widespread use of LTE devices and the growing needs of users,a scheme is proposed to improve the sensitivity of LTE diversity reception.By using an amplifier with extremely low noise coefficient and high gain,and adopting a two-stage cascade,the noise coefficient of the whole machine is reduced,thus improving the sensitivity of the receiver.The theoretical analysis and test of the receiver show that the scheme has the characteristics of simple structure and high index,and can be extended to all kinds of wireless receiver products.
