Staggered multitone (SMT) is sensitive to the carrier frequency offset (CFO). Differ ent from orthogonal frequency division multiplexing (OFDM), in SMT systems, CFO causes both intercarrier interference (ICI) and intersymbol interference (1ST). In this paper, we study the sensitivity of SMT to the phase offset. We derive a relationship be tween the total interference and the phase offset. We show that, without CFO, the total interference power due to the phase offset is a sinusoidal function. In the presence of CFO, the phase offset changes from symbol to symbol and the total interference power. is different for different SMT symbols. We use computer simulations to compare the sensitivity of SMT and OFDM systems to the phase and carrier frequency offset. The results show SMT experiences bigger interference power than OFDM.
