Patent ID: 8553751

Claim:
A radio equipment controller comprising: 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, wherein the detector compares data stored in the buffer with data derived from the data stored in the buffer being delayed by a specific offset length, and detects, as the OFDM symbol beginning, data stored in the buffer subsequent to the last data that matches when data that matches is a cyclic prefix (CP) length portion.
