随着60 GHz毫米波无线通信技术的成熟
其在无线传感器网络领域占据的地位日益增高。60 GHz通信系统的符号传输速率高达Gbps量级
为了降低系统复杂度
需要尽量减少每个符号的采样点数。此外
由于待处理的符号速率过高
传统串行定时同步方案受工作时钟约束而无法采用。为此
提出一种基于两倍过采样率的FIFO控制式并行定时同步方案
解决了超高速并行定时同步设计时遇到的时钟频率调整问题。设计的并行定时同步方案具有结构简单、实现复杂度低、同步所需时间短和鲁棒性高等优点
对60 GHz毫米波系统全数字解调器的设计具有较强的应用价值。同时
通过Matlab Simulink仿真
验证了提出的并行定时同步方案的可行性。
With the maturity of 60 GHz millimeter-wave wireless communications
it plays an increasingly important role in wireless sensor networks.In order to simplify the system complexity
it is necessary to decrease the sampling rate since the symbol transmission rate of 60 GHz communications system is up to Gbps.In addition
due to the high symbol rate
the traditional serial timing synchronization scheme cannot be adopted for the clock constraint.A FIFO controlled-parallel timing synchronization scheme based on twice-oversampling is proposed
which solves the clock frequency adjustment problem encountered in design of ultra-high-rate parallel timing synchronization.The scheme has the advantages of simple structure
low complexity
short synchronization time
high robustness
et al.thus it has strong value in the design of all-digital demodulator for 60 GHz millimeter-wave systems.Meanwhile
simulation results on the Matlab Simulink platform verify the feasibility of the proposed parallel timing synchronization.
