Abstract

The time domain synchronous orthogonal frequency division multiplex (TDS-OFDM) modulation scheme has recently been proposed in a new digital television (DTV) system. The European DTV standard DVB-T, on the other hand, uses the cyclic prefix (CP) OFDM modulation. In this paper, TDS-OFDM and CP-OFDM for nonergodic broadcast inter-symbol-interference channels are compared from an information theoretical perspective. The outage probability expressions are derived for both schemes and evaluated numerically under various system configurations and channel distributions.
