Convergence behaviour of linear parallel cancellation in CDMA
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270)
In this paper, the convergence behaviour of linear parallel interference cancellation is investigated. Especially the so-called ping-pong effect where the bit error rate performance is found to oscillate between two different convergence patterns is studied in detail. This effect is shown to be a direct consequence of the extreme eigenvalues of the correlation matrix, allowing for an analytical approach. Intervals for the dominating eigenvalues within which ping-pong effects can occur aredoi:10.1109/glocom.2001.966007 dblp:conf/globecom/RasmussenO01 fatcat:gjytwvy5rzcf5bkfdizg5kspse
