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.

说明：  基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明，当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器，由于用这种计算器来做移位计算比加法快，他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)
