Radio equipment controller, radio control method, radio station, and radio communication system
Abstract:
A radio equipment controller includes a calculator that calculates a delay amount by subtracting from a given maximum delay amount an internal delay amount of a radio equipment and a delay amount of a cable, the radio equipment modulating and transmitting orthogonal frequency division multiplexing (OFDM) symbols, and the cable connecting the radio equipment and the radio equipment controller that creates the OFDM symbols, a detector that detects a beginning of the OFDM symbols from data that is inputted into a buffer that stores data of the OFDM symbols, and a delay controller that determines a transmission timing of the OFDM symbols so that the transmission timing of the beginning of the OFDM symbols becomes a timing that is delayed by the calculated delay amount after a reference signal with a specific period.
