Abstract :
A multiuser detector based on Schur algorithm is studied in this paper. Because the computational complexity of the conventional decorrelating detector is high while computing the inverse of system matrices, especially when the system is asynchronous and the number of users is huge. The simulation results show that the performance of the multiuser detector based on Schur algorithm is similar to that of decorrelating detector, but it´s computational complexity is much lower than decorrelating detector´s.
