A robust and efficient technique for frame/symbol timing and carrier frequency
synchronization in OFDM systems is presented. It uses a preamble consisting of only one …

Synchronization is critical in the design of an OFDM receiver. Large timing offsets result in a
loss of orthogonality between subcarriers, ISI, and severe bit error degradation. To minimize …

A robust symbol-timing and carrier-frequency synchronization scheme applicable to
orthogonal frequency-division-multiplexing systems is presented. The proposed method is …

In this paper, we propose an efficient scheme using a new single-symbol preamble structure
for OFDM data-aided synchronization. The preamble symbol is constituted of two successive …

Orthogonal frequency division multiplexing is considered to be an appealing modulation
technique for high-speed wireless communication systems owing to its spectral efficiency …

We present three joint tracking algorithms of carrier frequency and sampling clock offsets for
OFDM-based WLAN systems, such as IEEE 802.11 a standard. In such systems, one symbol …
