Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A radio control device comprising:
at least one processor; and
at least one memory storing instructions executable by the at least one processor to:
perform delay control on radio data according to a first delay time that is less than a basic frame unit processing time, in units of basic frames of a CPRI (Common Public Radio Interface) frame, based on a desired data transmission timing in a radio device; and
multiplex the radio data that has undergone the delay control, wherein
the delay control is performable on the radio data according to a plurality of delay times less than the basic frame unit processing time, and
the instructions are executable by the at least one processor to further:
select the first delay time from the plurality of delay times, based on the desired data transmission timing;
store a plurality of tables that each include a plurality of tap coefficients corresponding to the plurality of delay times;
select, from the plurality of tables, the table retaining the plurality of first tap coefficients, based on the desired data transmission timing; and
implement a digital filter in which the plurality of first tap coefficients corresponding to the first delay time are set for a multiplier.
