In response to the growing demand for low-cost low-power wireless sensor networks and related applications,we develop bit and power loading algorithms that minimize
transmit-power for orthogonal frequency division multiplexing (OFDM) under rate and error probability constraints.Our novel
algorithms exploit one of three types of channel state information at the transmitter (CSIT): deterministic (per channel realization)for slow fading links, statistical (channel mean) for fast fading
links, and quantized (Q-) CSIT whereby a limited number of bits are fed back from the transmitter to the rece...
