摘要

本文提出了一种OFDM系统功率负载的码本设计方法。首先介绍了各子载波的平均误码率和信噪比之间的关系。在误码率准则的基础上,利用中心极限定理推导了功率负载的码本设计。与传统的功率加载码本相比,该码本在统计上达到了误码率的最优,设计复杂度低。

Power Loading Codebook Design for OFDM System
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.
