Abstract
A signal generator includes a memory for storing content information in the form of vectors including in-phase and quadrature elements of an orthogonal frequency division multiplexing waveform, a processor for converting the vectors to a radio frequency signal, and a logic device for controlling the operation of the memory and the processor. The in-phase and quadrature elements represent baseband content of the orthogonal frequency-division multiplexing waveform.
