Abstract
Due to ever-increasing data rates in wireless communications and simultaneously increasing number of users, centrally coordinated systems suffer from large controlling overhead. This fact will become even more dramatic in the future as Machine-Type Communication (MTC) is expected to connect several billion devices worldwide. In this paper, we research asynchronous systems with transmit-only devices and therefore without controlling and feedback from the base station. In such feedback-less networks, signal collisions are inevitable and pose a major challenge for system design. We derive a closed-form solution for the Bit Error Probability (BEP) of multiple colliding signals modulated with Filter Bank Multicarrier (FBMC), a scheme well suited for MTC since it enables parallel channel access for multiple devices. The system presented utilizes scattered pilot-based channel estimation for equalization with auxiliary pilots. We compare the BEP with equalization based on perfect channel knowledge. The results are valid for any numbers of colliding FBMC signals over a broad range of channel configurations.
