Proposal for MAC frame parameter design based on OFDM signaling and synchronization error criteria

Nowadays, communication systems are usually implemented by digital modulated waveforms. Such is the case of OFDM, where the spectrum efficiency and the robustness against undesirable channel effects are the main reported advantages to improve the quality and data rate of transmission. However, OFDM demands for accurate synchronization methods, otherwise intersymbol and intercarrier interference will degrade the achievable capacity of the transmission. The impact of synchronization errors must be considered while designing a system based on OFDM waveforms for the performance guarantee. In this direction, this work addresses a selection strategy of main MAC frame parameters regarding preamble and payload length under OFDM signal transmission with synchronization errors. This selection strategy is proposed to assist designers in the choice of proper MAC frame parameters that best fits into their own restrictions.
