Abstract
A method for the automatic scaling of radio receiver characteristics. Receiver designs are subject to change based upon the parameters of transmitters and the desired characteristics of communications links in a communications system. The method of the present invention involves automatically scaling the characteristics of a receiver based upon the transmitter proposed and the desired characteristics of a communications link. Auto-scaling calculates the bandwidth necessary for the receiver based upon the transmitter proposed. Information concerning the modulation type and the scaling factor associated with each modulation type are stored in a database for access by the system. Once transmitter characteristics are known, receiver characteristics are automatically calculated. The system allows for multiple designs to be created so that analysts can select the optimal design for the mission. The system also allows for animated soft copy output of maps, reports and graphs to be created as well as allowing for hard copy output of reports graphs.
