本文在卡尔曼滤波理论的基础上,分析了用单片 TMS320实现速率高于1200b/s 的短波 MODEN 中信道自适应均衡的可能性,并根据 TMS32020的特点,指出了在编程中提高精度及运算速度的方式。最后给出了用 TMS32020实现均衡器的电路原理图及计算机模拟结果,从而为高速数传进行短波信道实时均衡提供了一有效的途径. On the basis of Kalman filter theory, this paper analyzes the possibility of channel adaptive equalization in short-wave MODEN with single-chip TMS320 at higher than 1200b / s. According to the characteristics of TMS32020, Speed ​​of the way. Finally, the circuit diagram and computer simulation results of the equalizer are given with TMS32020, so as to provide an effective way for real-time short-wave channel high-speed data transmission.
