Concatenated “MMSE-Sequential Search” Algorithm for Multi User Detection in SDMA Uplink
Ilia G. Iliev, M Budzevski · 2011
The concatenation of MMSE and sequential search is MUD method which combats the imperfect channel conditions and maintains low complexity at the receiver. In this work the combination of two methods is proposed, and it is regarded in Spatial Division Multiplexing Access scheme. The suppression of Multi Access Interference and MMSE error along with BER performance is studied in case of different number of users and receiving antennas.
