摘要：
In this paper, a blind algorithm is proposed for channel and CFO estimation in zero-prefix OFDM systems. By exploiting the greatest common divisor structure of the received signal for two or more symbols, the algorithm yields joint estimates of channel parameters and carrier frequency offset. It provides error-free message recovery at moderate SNRs.
