Frequency offset estimation method, communication apparatus, wireless communication system, and program
Abstract:
A frequency offset estimation unit estimates a frequency offset by combining information on a maximum window having a maximum peak power obtained from a received PRACH (Physical Random Access Channel) signal and a sign of a phase of a correlation value between channel estimation values obtained from a received PUSCH (Physical Uplink Shared Channel) signal.
Abstract(Chinese):

频率偏移估计单元通过将从接收的PRACH（物理随机访问信道）信号获得的具有最大峰值功率的最大窗口的信息与从a获得的信道估计值之间的相关值的相位的符号组合信息来估计频率偏移 接收到的PUSCH（物理上行链路共享信道）信号。
