Abstract :
In this paper, we show how to compute the minimum complexity (in terms of the number of paths kept) for near optimal M-algorithm multiuser detection. Several proven properties of the vector Euclidean distance (VED) are utilised to give an efficient algorithm for computing the minimum VED leading to a value for the minimum required number of paths to be kept for a given number of users. The analytical results are supported by the simulation results
