Throughput Enhancement in Multi-Carrier Systems Employing Overlapping Weyl-Heisenberg Frames

A methodology for doubling the throughput of multi-carrier systems is proposed. Throughput enhancement method is introduced by using pulse shaping in multi-carrier systems. By employing more than one Weyl-Heisenberg frames that are orthonormal both within the frame and in between the frames, the throughput of multi-carrier systems is increased. Different lattice density scenarios are investigated for throughput enhancement. It is shown that by employing the proposed methodology, throughput of a multi-carrier system can be doubled. Theoretical analysis quantifying throughput enhancements are presented and results are supported by simulation studies. A system level comparison is presented for IEEE 802.16 standards. The effects of various impairments are investigated.
