    摘要: The present invention relates to filter, coherent receiver device and coherent receiving method. The filter is used for converting a partial response signal into a full response signal, wherein the filter uses the following transfer function HPre-Filter(z) with respect to a partial response signal having a transfer function H PR  ( z ) = A  ( 1 + z - 1 ) m  ( 1 - z - 1 ) n :   H Pre - Filter  ( z ) = 1 A  ( 1 + α   z - 1 ) m  ( 1 - α   z - 1 ) n , in which A is other item, m and n are integers larger than or equal to 0 but not being 0 at the same time, 0
