Patent ID: 8442093

Claim:
A method of processing a received time-hopping ultra-wide band (TH-UWB) signal comprising: for each of N s , time hopped representations of an information symbol in the TH-UWB signal where N s ≧2, generating a respective correlation output; performing a soft-limiting operation on each correlation output to produce a corresponding soft-limited correlation output; for each information symbol, generating a decision statistic using the soft-limited correlation outputs; making a decision on the information symbol based on the decision statistic and outputting the decision; wherein performing a soft-limiting operation on each correlation output to produce a corresponding soft-limited correlation output comprises determining: r ~ m = {  S m  , if ⁢ ⁢  S m  ≤ r m r m , if ⁢ -  S m  < r m <  S m  -  S m  , if ⁢ ⁢ r m ≤ -  S m  where r m is the correlation output for the mth representation and S m is the desired signal component for the mth representation, where m=1, . . . , N s .
