摘　　要：提出了一种适用于TDS-OFDM系统的AGC模块的算法设计。针对TDS-OFDM系统中3种信号帧的帧头能量不同的情况,对通用AGC模块进行设计改进,增加了帧头检测和跳过处理。仿真结果证明,AGC模块的跟踪锁定性能稳定,帧头的能量完全保留,该设计取得了良好的效果。A kind of algorithm design that is suitable for AGC module of TDS-OFDM system is put forword.Aiming at the circumstance of different frame head energy of three kinds of signal frame in TDS-OFDM system,general AGC module design is improved,increasing the frame head detection and skipping processing.The simulation results show that the tracking locking perfonnance of AGC module is stable,the energy of the frame head is completely preserved,the design has achieved good effect.
