Abstract :
In this paper, we present a codebook designing of power loading for OFDM systems. We first introduce the relation between average BER and SNR on each sub-carrier. Based on the criteria of bit error rate, codebook designing of power loading using central limit theorem is derived. Comparing with traditional codebook for power loading, this new one can attain optimum of error rate statistically and it can be designed with low complexity.
