Scalable Architecture of MIMO Multi-carrier CDMA System on Programmable Logic

In this paper, a scalable architecture of the multi-carrier CDMA system using multiple-input-multiple-output (MIMO) technology is designed in the programmable logic array. The system-level partitioning with different architecture design entries is described. The overall computing architecture for complex signal processing blocks, e.g., channel estimation, frequency domain equalization, demodulation etc is described. The MIMO architecture is easily extended from a SISO system with single antenna. This scalable architecture demonstrates resource utilization efficiency and easy extension to MIMO configurations.
