• Resumen

  • In this paper, we present a new hybrid modulation, called MPDWM (Multi-Pulse Dual width Modulation). The proposed method is based on a new algorithm for symbol encoding, to enumerate the maximum number of symbols that can be generated by the combination Position-Width, which improves the data rate, and also to implement symbol synchronization, without specifying a pulse for this purpose. Principles of encoding algorithm will be clarified, the formulas of power and bandwidth requirements will be presented, comparison results to MPPM will be also analyzed.
