摘要
针对TDS-OFDM系统的信道估计与数据循环化算法提出了一种硬件实现架构,其中循环相关的实现架构速度快且节省硬件资源。为了易于硬件实现,对迭代干扰消除提出了近似算法。仿真结果表明,此近似算法几乎没有造成性能损失。
In this paper, a VLSI architecture for channel estimation and cyclic restoration in TDS-OFDM is proposed. The realization of cyclic correlation introduced is high-speed and low-cost. An approximate algorithm of interference cancellation is proposed to implement on FPGA easily. And simulation shows that it has little lose in performance.
