The FBMC generation techniques are found to surmount the disadvantages of the IFFT/FFT based OFDM system. The minimization of PAPR is a much sought after solution by all multi-carrier methods. This paper investigates the possibility of a unified approach for error control coding and PAPR minimization in an FBMC-OQAM system. A new coding procedure called Constrained Message Length (CML) coding is presented in this paper. A new perspective on PAPR and an analytical framework for estimating the PAPR is also presented. Hybrid techniques using coding and companding are tested for different channel models, and their BER performance is on par with the BCH system. The proposed system is of low complexity and has a PAPR of only 3.81 dB, which is better than or comparable with the existing systems that are using complex methods. This paper has uniquely investigated the dependence of PAPR on the input data variation for a different set of random data loads. The CML coding proposed here can minimize the input data dependent PAPR deviation to a low variance of 0.045 dB, which provides an increased linear region of operation to the power amplifier in the RF section.

发现FBMC生成技术克服了基于IFFT / FFT的OFDM系统的缺点。所有多载波方法都极力追求PAPR最小化。本文研究了在FBMC-OQAM系统中采用统一方法进行差错控制编码和PAPR最小化的可能性。本文提出了一种新的编码过程，称为约束消息长度（CML）编码。还介绍了有关PAPR的新观点和估算PAPR的分析框架。使用编码和压扩的混合技术已针对不同的信道模型进行了测试，其BER性能与BCH系统相当。所提出的系统具有低复杂度，并且具有仅3.81 dB的PAPR，优于或与使用复杂方法的现有系统相当。本文对一组不同的随机数据负载下PAPR对输入数据变化的依赖性进行了独特的研究。这里提出的CML编码可以将取决于输入数据的PAPR偏差最小化到0.045 dB的低方差，这为RF部分中的功率放大器提供了增加的线性工作区域。
