摘要
The decoding of an UWB-IR signal modulated through a transmitted reference (TR) modulation scheme, comprises subtracting from the UWB-IR modulated signal, a version of said UWB-IR modulated signal delayed with a delay corresponding to the delay used in the TR modulation scheme, and decoding the resulting signal by using a non-coherent detection. Further for providing a more energy efficient way of transmitting information, a method of coding information to be conveyed by an UWB-IR signal, comprises sending within each Pulse Repetition Period (PRP) a reference pulse followed by a pulse train including at least two mutually delayed information pulses. A non-coherent detection may also be used for decoding a signal modulated through a TR-BPPM modulation scheme.
