美国海军开发的雷达传输损耗预测、计算软件AREPS的说明(The Space and Naval Warfare System Center, San Diego has a full spectrum research and development program with a long and proud history of rapidly responding to critical fleet requirements and deploying systems to address these requirements. One such system is the new Advanced Refractive Effects Prediction System (AREPS).)

In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization is an essential procedure for normal operation of the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.
