FBMC physical layer : a primer

Main Objectives

Physical layer best suited to the new concepts of dynamic access spectrum management and cognitive radio is needed for future efficient wireless and mobile radio networks The requirements of high data rates and flexible spectrum allocation are met by multicarrier techniques, which can approach the theoretical capacity limits in communications. The scheme used so far, Orthogonal Frequency Division Multiplexing (OFDM), is a block processing technique, which lacks flexibility and has poor spectral resolution. In contrast, a filter bank-based multicarrier (FBMC) technique offers high spectrum resolution and can provide independent sub-channels, while maintaining or enhancing the high data rate capability. In the project, a short term objective is to develop and demonstrate algorithms for single and multiantenna terminals, scalability and adaptivity, and multiple access. In the longer term, the impact on cognitive radio will be investigated.

FBMC has the potential to fulfil the requirements of the new concepts, but a major research effort is necessary for full exploitation and optimization in all aspects of the radio context. The physical layer is the basis on which the networks are built and, with the numerous scenarios and environments, a complex and coherent set of techniques and algorithms has to be worked out. Therefore, the effort is carried out at the European level, in order to benefit from the vast amount of knowledge and experience available and make the time scale compatible with the on-going or planned standardization actions. The consortium has a strong academic participation, whose mission is to deliver the best methods and the most efficient algorithms. The industrial partners bring their experience in communication infrastructure design and deployment, in instrumentation and measurements and in circuit design. Non-profit research organizations facilitate the cooperation between academic and industry partners. The success of the proposed physical layer will contribute to the dissemination and exploitation of the new radio concepts and to the advent of improved environment friendly services to the users
