Multiuser detection

From Wikipedia, the free encyclopedia

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]
