Simple Module PhyLayerUWBIR

Package: org.mixim.modules.phy

C++ definition

A physical layer that models an Ultra Wideband Impulse Radio wireless communication system.

This class loads channel models and delivers frames to an UWB Decider. It is independent of the modulation technique, as long as the frames are represented using the same approach as in IEEE802154A.h (Maximum Pulse Amplitude Estimation).

Several channel models are possible: Ghassemzadeh-LOS, Ghassemadeh-NLOS (see UWBIRStochasticPathlossModel.h) and the IEEE 802.15.4A UWB channel models that use the default power delay profile (see UWBIRIEEE802154APathlossModel.h).

Currently, an energy detection receiver is modeled in UWBIRED.h. Several synchronization logics have been implemented in derived classes: see DeciderUWBIREDSync.h and and DeciderUWBIREDSyncOnAddress.h.

To add a novel receiver (e.g. coherent demodulation), either derive UWBIRED or write a new one, then add functionality in this module to load the new decider. The same procedure applies for new channel models.

To change the modulation, see UWBIRMac.h, IEEE802154A.h and UWBIRED.h.

To implement optional modes of IEEE802154A, see IEEE802154A.h.
