N2 - Previously the SAGE algorithm was applied to sub-optimal yet efficient Joint data Detection and channel Estimation (JDE) for DS-CDMA of moderate time complexity. Modifying the expectation and maximization steps of the SAGE-JDE scheme, it is possible to obtain an efficient receiver architecture that can be implemented in a mobile terminal with linear time complexity in the number of users per demodulated bit. Monte Carlo simulations in a frequency-selective scenario show that the appealing properties of this so-called Simplified SAGE-JDE scheme like fast convergence and robustness against channel estimation errors remain.
