Power-efficient OFDM via quantized channel state information
AG Marques, FF Digham… - 2006 IEEE International …, 2006 - ieeexplore.ieee.org
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 …
