本程序主要是实现xinlinx fpga与dsp之间的双工通信(This program is to achieve duplex communication between xilinx fpga and dsp)

讲述软解调很不错的一片文档，主要阐述的是8PSK的软解调FPGA实现，但对8PSK的软解调原理阐述很清楚，没有多余的东西，但需要注意其中各个调制符号点得顺序。(About soft demodulation of a document is very good, mainly on the soft 8PSK demodulation FPGA, but soft 8PSK demodulation principle describes very clearly, no extra stuff, but need to pay attention to the point where each modulation symbol was in order.)
