Abstract:

为降低在定时同步算法实现时,截位对性能的影响与定时同步算法实现的复杂度,对定时同步实现时的内部子模块进行了讨论,对通过现场可编程门阵列(FPGA)实现定时同步算法的复杂度,按照单位时间内乘、加次数的方法进行了分析,并对多个定时同步模块间的关系进行了研究,提出了一种OFDM系统定时同步实现的自适应多点截位方法与2种MIMO-OFDM系统定时同步算法的简化实现方案,对实现方法在Xilinx公司的VirtexIIPro系列FPGA中的资源使用情况进行了统计,并在B3GTDD试验验证平台上进行了验证.验证结果表明,该实现方案可用于B3GTDDMIMO-OFDM系统定时同步算法的硬件实现.
