ABSTRACT:
The method is for decoding an incident UWB signal including successive incident pulses respectively received during successive Pulse Repetition Periods (PRP). The method includes determining a correlation matrix, whose terms respectively represent the correlation between all the M possible symbols transmitted in a current (PRP), and at least in the previous and in the next (PRP), and performing a correlation between an incident current pulse received during a current PRP and the M possible symbols transmitted in the current PRP and at least in the previous and in the next PRPs for obtaining a correlation vector. The method also includes preprocessing the correlation vector including reducing the effect of ISI from the correlation vector by using the correlation matrix, and decoding the preprocessed correlation vector for obtaining the bits of the transmitted symbol included in the incident received current pulse.
