Signal processing algorithm of high speed digital circuit in physical layer

In this paper, the author studies about the digital signal processing algorithm of high speed digital circuit in physical layer. At present, the digital signal processing has applied extensively in many subjects such as communications, radar, sonar, speech and image processing etc. In order to solve the problem of performance degradation which arises from sequence truncation in many digital signal processing occasions, this paper prompts an algorithm for the digital signal processing algorithms of high speed digital circuit in physical layer. The experiment result shows that the performance can be improved by using this algorithm.
