Abstract

A system and method involve receiving a plurality of samples of at least one orthogonal frequency division multiplex (OFDM) signal, the samples containing at least one complete OFDM symbol including data samples and a cyclic prefix comprising inter-symbol interference (ISI) samples and one or more ISI-free samples, and determining a symbol time offset estimate θ that minimizes the squared difference between the ISI-free samples and their corresponding data samples and satisfies a correlation based boundary condition.
