Multiuser detection

Multiuser detection

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