ABSTRACT:
An error correction system for a multicarrier radio transmission system is provided. At the transmission end, a frame alignment bit and error correction bits are added to each of the signals from a serial/parallel converter. Positions of the frame alignment bits in the signals are controlled by a common frame counter. The signals added to frame alignment bits and error correction bits are radio transmitted on several carriers. At the receiving end, frame alignment of each demodulated signal is established based on demodulated signals transmitted on two carriers. Therefore, even if one carrier is deteriorated, frame alignment of data signals on the carrier can be established based on the frame alignment bit in the other data signal on the intact other carrier.
