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.

BPSK信号的仿真，包括随机信号产生、数字基带信号、已调信号、加噪声，解调等(BPSK signal simulation, including the random signal generator, a digital baseband signal, the modulated signal, plus noise, the demodulation)
