Method for implement of RRC filter using linear programming

摘要

PURPOSE: A method for implementing an RRC(Root Raised Cosine) filter by using a linear programming is provided to implement an RRC filter by using a linear programming, thereby using all maximum tabs provided from a DSP transceiver and configuring the RRC filter by using a relatively small number of tabs. CONSTITUTION: A system calculates transmission characteristics of an ideal RRC filter(ST11). The system defines an RRC filter to be substantially implemented(ST12). The system expresses a difference between the ideal RRC filter and the defined RRC filter as an error value(ST13). The system converts the expressed difference in matrix type so as to be processed in a linear programming(ST14). The system obtains RRC filter tabs for minimizing the error value by using the linear programming(ST15).
