| 发明名称 | Frequency offset acquisition method and apparatus thereof | ||
| 摘要 | A frequency offset acquisition method includes: receiving a specific sequence signal transmitted through a channel; shifting a frequency of the specific sequence signal at a plurality of different frequencies in frequency domain to thereby generate a plurality of shifted sequence signals respectively; and determining an estimated frequency offset value between a transmitter and a receiver according to the shifted sequence signals. | ||

| 主权项 | 1. A frequency offset acquisition method, comprising: receiving a specific sequence signal transmitted through a channel, and storing the specific sequence signal in a storage unit; performing a plurality of frequency shifting operations upon the same and entire specific sequence signal by respectively shifting the same and entire specific sequence signal by a plurality of different frequencies in frequency domain, thereby generating a plurality of shifted sequence signals, respectively; and determining an estimated frequency offset value between a transmitter and a receiver according to the plurality of shifted sequence signals. | ||
