In recent years mobile radio communication systems have become increasingly important thanks to their pervasiveness, attracting interest and going through constant changes to keep up with technological development and user demands. Characterized by ever higher date rates (up to tens of Gbps) it is important to ensure speed and reliability at the lowest possible cost. The use of Orthogonal Frequency-Division Multiplexing (OFDM) digital transmission gives the opportunity to encode data on multiple carrier frequencies, thus allowing to broadcast data in parallel. Additionally, compared to the single carrier systems, it introduces a series of advantages, such as immunity to selective fading and spectrum efficiency, that makes its use very common in many existing high data-rate standards, e.g.
