On sounding in wideband channels

(cont.) This approach provides us with a cohesive framework to consider the relative costs and benefits of allotting energy for sounding versus transmission, and for repeated sounding of a single channel versus sounding of various different channels. In particular, we are able to give both an upper bound and a lower bound on the number of subchannels that should be probed for capacity maximization in terms of the available transmission energy, the available bandwidth and the fading characteristics of the channel. Moreover, the two bounds are so close to each other that they may well be treated as an approximation to the desirable number of subchannels to probe.
