Wideband SIC (cont..)
Based on the concept of signal regeneration
Regenerated wideband signals for all the users are subtracted from the input signal to produce Residual signal
Residual signal does not have signal energy from any of the tracked users
Residual signal is added back to the individual multipath component of a given user to give a cleaned wideband signal for the user
This scheme requires spreading code of different users as well as their multipath delays
This scheme can be used with both long and short spreading code
