Abstract

Wireless application of orthogonal frequency division multiplexing (OFDM) is gaining much attention as a modulation technique for high speed data transmission in various applications due to its good properties against frequency selective fading, intersymbol interference (ISI), and intercarrier interference (ICI). Although, there are still several issues related to synchronization and multiple access that require more research. In focus of this, in this paper, we investigate the performance of OFDM transmission through slotted ALOHA multiple access and compare the results to unslotted ALOHA OFDM systems. The results show that the OFDM slotted ALOHA technique has advantages in SNR, throughput, and frame synchronization performance compared to unslotted ALOHA with OFDM, which suggests slotted ALOHA as a candidate for multiple access for OFDM wireless communication applications.
