Exploiting Sparse User Activity in Multiuser Detection
—The number of active users in code-division multiple access (CDMA) systems is often much lower than the spreading gain. The present paper exploits fruitfully this a priori infor...

Low-complexity receivers for multiuser detection with an unknown number of active users
In multiuser detection, the set of users active at any time may be unknown to the receiver. A two-step detection procedure, in which multiuser detection is preceded by active-user...
