Multicarrier modulation techniques are particularly appropriate for realization of broadband communication systems . Nowadays , Orthogonal Frequency Division Multiplexing (OFDM) , as the most famous example , has been adapted in various communication standards , i.e. , ADSL , IEEE802.11a , 802.16 and LTE . However , because of some shortcomings of OFDM , Filter Bank Multicarrier (FBMC) has been suggested as an alternative technique . Several systems of FBMC have been introduced . The most spectrally efficient one is staggered modulated multitone (SMT) which is also known as FBMC/OQAM or OFDM/OQAM . There are two structures to implement SMT , polyphase structure and frequency-spreading (FS) . In this thesis , after an introduction to FBMC systems and specially SMT , both structures of SMT are presented . Since , impact of Carrier Frequency Offset (CFO) and Timing Offset (TO) are important issues in multicarrier modulation systems , sensitivity of two structures of SMT to these offsets is evaluated and compared by the Signal to Interference Ratio (SIR) . Then , robustness of the two structures against these two offsets in presence of AWGN and multipath channel is clarified . Finally , an alternative method is proposed to compensate CFO for FS structure of SMT Multiple Access (SMTMA) in the uplink of multiple access scenario . The proposed method reduces the computational complexity and the latency of receiver without losing the performance . Moreover , a possibility for combining the compensation of TO and channel effects with CFO correction is presented . Simulation results show that the proposed method offers a reasonable performance and improvement . Keywords: FBMC , OFDM , SMT , FS structure , CFO , TO .
