Abstract
The present invention relates to method of transmitting and receiving signal and apparatus thereof. In one aspect of the present invention, the method of receiving a signal, includes demodulating received signals by Orthogonal Frequency Division Multiplexing (OFDM) method, transforming OFDM symbols in the demodulated signals into bitstreams, deinterleaving bits, which correspond to a Low Density Parity Check (LDPC) block of the bitstreams, and correcting errors in the deinterleaved bits of the bitstreams.
