FSLE and FSDF joint detectors for long code DS-CDMA
Luc Vandendorpe, François Horlin, T. Sartenaer · 2002
We investigate detection structures for a DS-CDMA. multiuser uplink using codes with a period of several symbols, named long codes. We first propose a multirate description of the uplink. Then based on this formalism we revisit a number of popular receiver structures: RAKE receivers, minimum mean square error linear and decision feedback fractionally spaced detectors.
