W-CDMA RADIO BASE STATION DEVICE AND WINDOW DISCRIMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a Window discrimination method that can realize Window discrimination with a light processing load. SOLUTION: FP (Frame Protocol) data frames are grouped so that the position and size of a Window of them are equal to each other, no Window discrimination is conducted for every reception of one FP data frame but the Window discrimination is conducted in a lot after the reception of all the FP data frames of a group is finished. When all the FP data frames enter the Window and the number of the FP data frames of the same group is N, number of Window discrimination times having been conventionally N is decreased to two so that the Window discrimination processing by (N-2) times can be saved.
