Abstract:
A transmission system using multicarrier modulation, comprising:a transmitter for transmitting symbols, said transmitter including a modulator for transforming complex amplitudes in the frequency domain to the time domain, a transmit symbol counter for counting the transmitted symbols, and a frame synchronization pattern source for providing a synchronization pattern to be transmitted as one of the transmitted symbols at a predetermined count of the transmit symbol counter; and a receiver for receiving the transmitted symbols and obtaining data therefrom, said receiver including a demodulator for transforming the received time domain values into complex amplitudes in the frequency domain, a receive symbol counter for counting the received symbols, and a frame synchronizer for extracting at least one of the received symbols containing the synchronization pattern from said transmitter at a time dependent upon the count of the received symbol count.
