OFDM is a practical and efficient modulation technology. Frequency synchronization for OFDM is very important because the carrier frequency offset (CFO) will damage the performance. Based on the correlation bewteen the front half-symbol and the back half-symbol, a cost function is deduced which varies with the carrier frequency offset as a sine function, and then a new carrier frequency offset estimation algorithm is presented. The papers will all be in a 2-column format and the final publication will be A4 size.
