Abstract:
A method of modulating digital data, comprising:a) providing first and second plurality of differently phased signals, said first and second plurality of differently phased signals both include first and second reference phase signals, said first plurality of differently phased signals differ from said first reference phase signal to said second reference phase signal by a respective first plurality of differing amounts, said second plurality of differently phased signals differ from said first reference phase signal to said second reference phase signal by a respective second plurality of differing amounts, and said first plurality of differing amounts are respectively equal in magnitude and opposite in sign from said second plurality of differing amounts; b) receiving digital data; c) applying said first and second plurality of differently phased signals to first and second non-linear amplifiers, respectively, when said received digital data changes state; and d) summing output from said first and second non-linear amplifiers.
