摘要: |
将Costas环与多相滤波相结合,提出一种并行结构,可以使环路滤波器以较低的工作速率获得较高的等效处理速率,对高速数字通信的载波同步有一定的借鉴意义。 |

A Parallel Costas-Loop Architecture for High Speed Digital Communications |
|
() |
Abstract: |
The Costas-loop and poly-phase-filter are combined,then a parallel architecture is presented.With this method,the loop-filter can achieve equivalent high processing rate while operating in low clock rate.This method can be used for reference in high speed digital communications. |
