Abstract:
Performance of coded Frequency-Division Multiplexed Continuous Phase Modulation (FDM-CPM) systems with Multiple Input Multiple Output (MIMO) transmission is investigated. The system is designed to achieve high spectral efficiency by exploiting the multiplexing gain of MIMO techniques. Moreover, a FDM MultiUser (MU) scheme with tight inter-carrier frequency spacing is used to increase spectral efficiency. It is shown that, using this scheme, significant improvement both in terms of bit error rate and spectral efficiency are obtained when compared to the single-antenna MU scenario. To take advantage of the multiplexing gain of MIMO systems, a Minimum Mean Square Error (MMSE) MIMO detector and a low-complexity iterative algorithm for Inter-Carrier Interference (ICI) cancellation are considered. Numerical simulations have been performed to assess the performance improvement achieved with the proposed frequency-division multiplexed CPM multiuser MIMO system.
