Abstract
Orthogonal pulse polarity modulation involves wireless communication in which the polarity of modulating pulses are set responsive to positive and negative character values of a corresponding code sequence. In a described implementation, data is converted to chip waveforms, spectrum lines are removed, and pulses are appropriately shaped. For example, a data bit stream may be converted into chip waveforms using a bit stream-to-symbol segmenter, a symbol-to-code sequence mapper, and a code sequence-to-chip waveform transformer. The polarities of respective individual chips in a given chip waveform match the signs of respective individual characters in a corresponding code sequence.
