An FPGA-based MIMO-OFDM with Golden decoding

With the development of communication technology, the rising interest in wireless communication for providing mobile as well as nomadic and fixed services for video, voice and data, a new system of MIMO-OFDM is designed for providing best-in-class performance attributes such as latency, capacity, peak and sustained data rates and corresponding spectral efficiencies, overall network complexity and quality-of service management. In this paper, we present a prototype FPGA design for an available Golden decoding implementation of a MIMO-OFDM technique. Some necessary concepts of MIMO-OFDM system which are involved in the Golden decoding are introduced. The module of Golden decoding is integrated and synthesized on Xilinx, Virtex5-XC5VSX95T FPGA. The simulation and debugging tool of Modelsim is used to verify the functionality of the Golden decoding module, the simulator analysis of ChipScope and the graph of constellation of 16QAM demapping are used to analyze the captured data.
