Performance Comparison and Study of UpLink Multiple Access

In the research of wideband wireless communication systems,there are four feasible multiple access methods for uplink system.They are SC-FDMA、OFDMA、Clustered SC-FDMA and Nx SC-FDMA.The principles of these methods,and compare their performance through numerical evolutions and simulations are analyzed,including the comparison of cubic metrics,complexity and the block error ratio.The results show that the OFDMA has the best performance of block error rate with the lowest complexity,but the corresponding value of cubic metrics is the maximum.The SC-FDMA has the minimum value of cubic metrics,but with the highest complexity and the worst performance for the bit error rate.The clustered SC-FDMA and the Nx SC-FDMA are the compromise of the OFDMA and the SC-FDMA.
