Abstract
Recently, a handful of wireless communication protocols that are seeking fundamental improvement in spectrum utilization adopted OFDMA (Orthogonal Frequency Division Multiple Access) as the multiple access technique for data transmission due to its high efficiency and flexibility. This research provides a general simulation framework for OFDMA Uplink and Downlink data transmission and analyzes the performance of the system under different configurations and various channel conditions. Specifically, we present our investigation of the effect of signal-to-noise ration and symbol timing offset, and we gauge the performance in terms of SER (symbol error rate).
