The present invention provides an orthogonal frequency division multiplex (OFDM) packet detect unit. In one embodiment, the OFDM packet detect unit includes a correlation indicator configured to cross-correlate a received symbol and a stored standard symbol to yield a correlation result. Additionally, the OFDM packet detect unit also includes a threshold discriminator coupled to the correlation indicator and configured to produce a packet detect signal for a fast Fourier transform (FFT) placement peak based on a comparison between the correlation result and a threshold.
