Abstract :
To better answer the user needs, new air interfaces are currently being selected for the emerging wireless communication systems. OFDM and SC-FDE are two interesting alternatives that support both the low complexity equalization of the multi-path channels. Even if the two systems benefit approximately from the same performance, they behave significantly differently in the presence of synchronization errors and front-end non-idealities. The goal of this paper is to assess the impact of CFO, SCO and IQ imbalance on the performance of the OFDM and SC-FDE systems.
