Abstract

A joint initial frame synchronization and initial channel estimation algorithm for OFDM systems is developed, and its performance with carrier frequency offset and with additive white Gaussian noise in frequency selective channels is evaluated. Transmission of a short pre-frame synchronization burst is proposed and slow fading is assumed, so that the channel can be considered time invariant for the duration of the synchronization burst
