OFDM/OFDMA TIMING SYNCHRONIZATION USING NON-CONSECUTIVE PILOT SUBCARRIER ASSIGNMENT

摘要

Systems and methods which are adapted determine timing with respect to an orthogonal frequency division (OFD) channel, such as may be used with respect to an OFDM or OFDMA systems through reliably identifying timing of a first arriving signal path. Embodiments use deconvolution to construct the channel impulse response associated with a received signal. The first arriving path for the received signal may readily and reliably be determined using the channel impulse response information.
