Abstract:
An orthogonal frequency-division multiplexing multi-carrier modulation method for digitalized TV signals includes converting serial TS code stream to parallel TS code stream, orthogonal phase modulation, perform TDFT, frequency domain interlacing, and parallel-serial conversion. Its advantages are low convergence error and short convergenic time.
