【Abstract】 A design method for a modem of 2DPSK by LHDL programming language in present. The principle and design method of the modem of 2DPSK are described in detail. According to our method, we carry out the Modem of 2DPSK based on complex programmable logic device (CPLD). In addition, the method of program design and the working wave of the modem obtained by simulator are given. The data transport rate and modulating method of carrier wave frequency of the modem are also described.更多还原
