摘要
随着无线通信标准的快速发展与各个协议中操作模式数量的激增,为特定模式设计专用芯片的成本和时间难以承受.同时,使用通用微处理器来进行信号处理的速度过慢,难以满足需要.本文尝试在动态可重构处理器架构上实现一种MIMO-OFDM系统中典型的信道估计算法,可以兼顾硬件实现的灵活性与处理速度的高效性.在28 nm工艺下以1 GHz的时钟频率仿真,其处理速度可达通用微处理器的8.8到14.6倍.
With the rapid development of wireless communication standards and the proliferation of operating modes in various protocols, the cost and time to design an ASIC for a particular mode is unbearable. At the same time, the use of a general-purpose microprocessor for signal processing is too slow to meet the needs. Therefore, this paper attempts to implement typical channel estimation algorithms in a MIMO-OFDM system on a dynamic reconfigurable processor architecture, which can balance the flexibility of hardware implementation and the efficiency of processing speed. It is simulated at a clock frequency of 1 GHz in 28 nm process, and its processing speed can reach 8.8 to 14.6 times of that of a general-purpose microprocessor.
