Abstract
To meet the demands of long distance broadband data transmission under aeronautical channel,a digital broadband receiver with 8 PSK modulation scheme is designed by using single carrier frequency do-main equalization ( SC-FDE) ,including transmission frame synchronization,carrier recovery,timing recov-ery,channel estimation and frequency domain equalization. Meanwhile,for flexible consideration,the varia-ble rate ability is designed by using numerical interpolation method. Based on implementation optimization for Xilinx field-programmable gate array ( FPGA) platform,the broadband receiver is accomplished,whose transmission rate covers 112. 5~900 Mbit/s. Numerical simulation analysis and hardware tests show that the receiver has a very good performance,and the SC-FDE scheme has the ability to well compensate the effects of multipath propagation and fits for applying in high dynamic aeronautical broadband wireless data transmission systems.关键词
