OFDM transmission/reception apparatus having a guard interval length changing function |
摘要 |
The subtractor of the reception system calculates the channel quality using an optimal guard interval length detection signal inserted into one carrier by the transmission system, then the optimal guard interval length detector calculates the minimum guard interval length necessary to eliminate delayed signals using this calculated channel quality, inserts the control signal indicating this guard interval length into one carrier and the reception system sets the guard interval length using this control signal.
