Yr. Zhang et al., Subspace training method for signature waveform estimation in multipath CDMA channel with coloured noise, ELECTR LETT, 36(10), 2000, pp. 902-904
A powerful subspace training method for signature waveform estimation and d
etection in slow fading multipath DS-CDMA channels is presented. By using a
small number of the desired user's training symbols, this method is comput
ationally efficient, near-far resistant and independent of interference noi
se.
