Abstract

In this paper, a comparative analysis of the performance of the non-synchronized initial random access channel in mobile WiMAX and E-UTRA systems under different conditions (fast fading, multiuser interference) is carried out. The analysis is focused on the correlation properties of the code sequences used in each case. We evaluate their ability to provide low values for false alarm and erroneous detection probabilities (detecting a sequence that has not been transmitted) at the same time as guaranteeing low non detection probabilities of the effectively transmitted sequences.
