| Abstract: | The encoding and decoding algorithms of space-frequency block coder（SFBC） are analyzed first,with emphasis on implementation of the decoding algorithm.An optimized decoding structure for SFBC codes decoder with higher speed and fewer chip resources is proposed,which could reduce the complexity and the requirement for chip resources.The algorithm structure could be easily implemented on the xc4vlx80 FPGA form Xilinx.Simulation results show that it is efficient and practicable. |
