Abstract :
In OFDM-based systems, bit allocation techniques are used according to channel response, as noisy sub-channels should carry little or no data. In this paper, we compare four different types of bit loading algorithms and analyze bit allotment per sub channel and energy consumed at a fixed bit error rate and fixed target total number of bits.
