Abstract
It is well known that for the Gaussian broadcast channel, timeshared coding is not as efficient as more sophisticated “broadcast” coding strategies. However, in this article we will show that the relative advantage of broadcast coding over timeshared coding is small if the signal-to-noise ratios of both receivers are small. One surprising consequence of this is that for the wideband Gaussian broadcast channel, which we shail define, broadcast coding offers no advantage over timeshared coding at all, and so timeshared coding is optimal.
