Efficient quadrature code position modulation |
摘要 |
A technique and apparatus for implementing code position modulation (CPM) on in-phase and quadrature-phase components of a radio frequency (RF) carrier. The technique simplifies the modulation/demodulation process by requiring only one pseudo-noise (PN) sequence to be stored in the transceiver device. As a consequence, only a single unique PN sequence needs to be stored in the transceiver, thus resulting in a reduction of circuit complexity.
