This course aims at delivering to the audience the in-depth analysis of various multicarrier modulations techniques, which can be considered for application in the future, flexible communications systems. Currently due to its great features Orthogonal Frequency Division Multiplexing (OFDM) technique has been already applied in various existing wireless and wired communication systems, such as DVB-T/T2/H, IEEE 802.11, IEEE 802.16, LTE, xDSL etc. Advanced future radio interface platforms with dynamic spectrum access (DSA) and sharing are considered to be the key technologies in making the best solution of the conflict between the inefficient usage of the frequency spectrum and the continuous evolution in the wireless communication.There is no doubt that multicarrier communication systems are considered as the most appropriate candidate for spectrum coexistence and secondary access for future cognitive systems due to its flexibility in allocating different resources among different users as well as its ability to fill the spectrum holes left by the primary users (PUs). However, the use of a multicarrier scheme with specific carrier shapes or another one will affect differently the overall performance of the communication system. Fortunately, investigations performed in many research centers and industries within the framework of European research projects such as PHYDYAS, URANUS, and EMPhAtiC have shown that these constraints can be alleviated e.g. by application of the so-called filter-bank based multicarrier signals. One of the main features of such approach is the great possibility for adaptation of various signal parameters (e.g. pulse shape, low out-of-band emission modulation techniques, spectrally adaptive and flexible modulation techniques, filtering techniques, etc.) which makes this solution suitable for application in future flexible radio communication systems.Therefore, the plan for the course is based on two parts. First part rises a simple but not minor question; %BFis OFDM the best scheme for spectrum sharing and system coexistence context? To answer such a question, the authors will first focus on basic theoretical aspects centring on the following: 1) basics aspects of OFDM system will be presented followed by the summary of the features of other multicarrier solutions (DMT, FMT, Lattice-OFDM etc.), 2) next, the main features of the of filter-bank based transmission (FB-MC) systems will be presented where aspects related to achieved capacity under different interference constraints and total budgets in comparison with achieved by OFDM. Second part of this course focuses on the use of advanced multicarrier wave forms for spectrum sharing and system coexistence having as a goal applications on: TV white space, Machine to Machine, future broadband Professional Mobile Radio(PMR)/(PPDR) systems, and beyond LTE.
