iterative multiuser detection using multinomial expansion in cdma systems

摘要

Method for iterative multi-user detection in CDMA systems using polynomial-expansion (PE) detectors. The number of iteration steps is reduced by estimation of certain Eigen-values of the system-matrix by use of a special structure for the system matrix. The estimations are based on Gershgorin's theorem. The estimations greatly increase convergence speed. The invention also relates to a corresponding detector with a chip and or a processor, a computer program product and a computer-readable storage medium on which the program is stored.
