Implementation of VHDL in ASK,FSK Modem Based on Random Number
By using the Virtex II-Pro series board which has the core of XC2VP30 FPGA,we can get the implementation of VHDL in ASK,FSK modem based on random number.In this method,without using special encryption and decryption chip,we can add a user-defined random number as sys_random.Compared with the traditional communications system which use a single ASK,FSK modem,this method can improve the security performance to some extent.
