The fast Walsh transform ( FWT) decoding algorithm and the field programmable gate array ( FPGA) hardware implementation of the CCK modulation/ demodulation system was proposed in the final. 最后给出了解码的FWT(FastWalshtransform)算法以及调制解调系统的现场可编程门阵列(FPGA)硬件实现。
The fifth one is encoding and decoding for Mode S.The whole system has been achieved by using the large-scale field programmable gate array ( FPGA) of Xilinx. 第五是对S模式校验码的正确编码和解码。整个系统是采用Xilinx的大规模现场可编程门阵列(FPGA)实现。
