Abstract: Method of decoding an incident UWB signal including successive incident pulses respectively received during successive Pulse Repetition Periods, each incident pulse including one transmitted symbol among M possible symbols, said transmitted symbol being corrupted by Inter Symbol Interferences (ISI), said method comprising the steps of: determining a correlation matrix (“), whose terms respectively represent the correlation between all the M possible symbols transmitted in a current Pulse Repetition Period, and at least in the previous and in the next Pulse Repetition Periods; performing a correlation between an incident current pulse received during a current PRP and the M possible symbols transmitted in said current PRP and at least in the previous and in the next PRPs for obtaining a correlation vector (Y); preprocessing said correlation vector (Y) including reducing the effect of the ISI from said correlation vector (Y) by using said correlation matrix (“); decoding said preprocessed correlation vector (Y") for obtaining the bits of the transmitted symbol included in said incident received current pulse.
