Abstract :
Based on the Neymann-Pearson criterion, a linear-complexity joint user identification, received timings, carrier phases and amplitudes estimation scheme is proposed without the limitations of existing approaches. Both mathematically and numerically, we justify the effectiveness of our proposed novel scheme for an arbitrary number of users in near-far environments.
