T. Felhauer et al., A LOW-COST METHOD FOR CDMA AND OTHER APPLICATIONS TO SEPARATE NONORTHOGONAL SIGNALS, IEEE transactions on communications, 42(2-4), 1994, pp. 881-883
In this paper, a low-cost linear algorithm for unbiased separation of
not necessarily orthogonal signals is proposed. A new view on the suit
ability of signals is opened which increases the variety of candidate
signals for e.g. CDMA applications. The proposed algorithm can be adva
ntageously implemented by a modified matched filter bank.
