Low-cost FPGA implementation of 2D digital pre-distorter for concurrent dual-band power amplifier
《The Journal of China Universities of Posts and Telecommunications》2016年第1期14-21,共8页Zeng Guang Yu Cuiping Li Shulan Liu Yuan'an 
supported by the National Natural Science Foundation of China(61201025);the National Natural Science Foundation of China for the Major Equipment Development(61327806)
This paper proposes a low-cost hardware architecture based on concurrent dual-band digital pre-distorter （DPD）. The architecture is implemented on field programmable gate array （FPGA） to compensate for the nonline...
