Low-complexity CFO correction of frequency-spreading SMT in uplink of multicarrier multiple access networks

This paper presents an alternative method to compensate carrier frequency offset (CFO) for frequency-spreading structure of staggered modulated multitone (FS-SMT) system in the uplink of multiple access scenario. The proposed method reduces computational complexity and latency of the receiver without losing the performance. Moreover, a possibility for merging compensation of timing offset (TO) and channel effect with CFO correction is presented. Simulation results show that the proposed method offers a reasonable performance with mentioned improvements.
