Abstract
A receiver for synchronous DS-CDMA systems is proposed with a decision window that is aligned to encompass two half bits of each user. Such a receiver is compared with the classical one in terms of Shannon capacity showing a definite improvement, Based on this, traditional upper bounds and optimality criteria on the capacity of synchronous DS-CDMA systems are revised.
