Abstract :
A trellis-coded orthogonal frequency division multiplexing (TC-OFDM) system is studied for digital video broadcasting with emphasis on mobile reception. Mobility causes time variations over the OFDM blocks that leads to an error floor due to inter-channel interference (ICI). The paper proposes some new trellis codes for TC-OFDM systems to combat the ICI and additive noise. It also investigates the feasibility of using multiresolution modulation (MRM) as a means for extending the broadcast range
