- about Carrier frequency offset(CFO)
QAM
- 该文给出了一种QAM信号载波频偏估计算法。-This paper presents a QAM signal carrier frequency offset estimation algorithm.
analisa
- This model shows the implementation of a QPSK transmitter and receiver. The receiver addresses practical issues in wireless communications, e.g. carrier frequency and phase offset, timing offset and frame synchronization. The receiver demodulates the
Offset-CS-Algorithm-in-LTE
- :LTE(Long Term Evolution,长期演进)系统中的小区初始搜索过程通过分别检测主同步信号(Primary Synchronization Signal,PSS)和辅同步信号(Secondary Synchronization Signal,SSS)来完成,搜 索结果包括小区组ID、符号定时、频偏估计、组内小区ID以及帧定时[1]。然而,若接收信号 1IDN 2IDN 中存在整数倍频偏,则由于时域的相位旋转,主
CFO-UFMC
- 本论文中,一个混合载波频率偏移估计方案用于基于通用滤波多载波的系统。 此方案所述CFO估计器基于最小平方(LS)准则首先导出以获得粗略频率偏移估计使用大频率搜索步骤。 接着,通过其精确估计残留频率偏移自相关操作补偿。 该算法具有较大估计的特点范围以及更高的估计精度。-In this letter, a robust hybrid carrier frequency offset (CFO) estimation scheme based on training symbols is devi
