ABSTRACT:
A device for modulating a carrier signal simultaneously performs frequency translation, upsampling, and pulse shaping. The device includes a mapper generating a first data signal. A complex mixer and an upsampling device are used to increase the data value frequency and spectrum shift the data signal. A finite impulse response filter operating on the data signal generates a digital signal representing the modulated carrier.
