System and method for frequency offset and symbol index estimation |
摘要 |
Scattered pilots are used to estimate the integer frequency offset and OFDM symbol index simultaneously. A cross-correlation between IFFT outputs of received samples with different spectral shift and OFDM symbol index is used to identify the channel impulse response. Upon determination of the channel impulse, the estimated integer frequency offset and OFDM symbol index can then be determined. |
