Methods and systems for time tracking in OFDM systems
Techniques proposed in the present disclosure may used to update an FFT window position and perform linear phase compensation for OFDM wireless systems with up to two antennas at the receiver. Techniques presented herein may help resolve a problem of determining an optimum FFT window position under the condition that the length of channel impulse response is larger than the length of cyclic prefix.
