摘　　要：针对航空信道具有复杂性和信号传输受多径效应的影响的问题,利用L-DACS1反向链路超帧中的导频,设计了基于LS算法的信道估计方法,使用数字信号处理芯片TMS320C6713在硬件设计实现了该方法,并应用于实际的项目中。测试结果表明,该方案可以有效的进行信道估计与均衡,满足L-DACS1高速传输中对可靠性的要求。Aiming at the problem that the aeronautical channel is complex and the signal is affected by multi- path effects during the transmission, a channel estimation method based on LS algorithm using the pilots in L- DACS1 frame is designed. This method, which is applied in a practical project, is implemented in hardware using DSP chip TMS320C6713. The result shows that this method of channel estimation can meet the reliability require- ments of L-DACS1 system during high speed transmission.
