CASCADED PHASE PULSE POSITION AND PULSE WIDTH MODULATION BASED DIGITAL TRANSMITTER

摘要

Briefly, in accordance with one or more embodiments, a digital transmitter may comprise two or more phase modulators in a cascaded arrangement. The phase modulators may modulate a local oscillator signal using control signals derived from the quadrature baseband data to be transmitted. A closed loop power control feedback arrangement may be used to compare the output power of the transmitter with a desired output signal, and make corrections to the output signal by modifying at least one of the control signals provided to the cascaded phase modulators.
