Multiuser detection

Multiuser detection (also known as joint detection) is one of the receiver design technologies for detecting desired signal(s) from interference and noise. Traditionally, single-user receiver design is known to suffer from the so-called near-far problem, where a nearby or strong signal source may block the signal reception of a far-away or weak signaled user. The near-far problem is more serious in CDMA-type wireless multi-user communication systems. Multiuser detection techniques can help the receiver solve this problem.[1]
