Digital carrierless amplitude and phase modulation (CAP) transmitter using vector arithmetic structure (VAS)

摘要

A method and apparatus for carrierless amplitude and phase CAP encoding of data in a manner avoiding the use of pulse shaping filters for in-phase and quadrature impulse signals. Specifically, in-phase and quadrature vector arithmetic structures (VAS) to adapt respective in-phase and quadrature impulse components to produce appropriate shaped in-phase and quadrature components.
