BFSK for modulation in digital signal processing

目前已经提出了许多不同的算法来解决OFDM 系统中的PAPR 问题，本章详 细介绍了其中的限幅法、压缩扩张法、星座图扩展法、选择性映射法和部分传输 序列法。在介绍每一种算法时，针对其主要存在的问题进行了相应的改进，使每 一种算法都成为比较实用的算法。(Has put forward a number of different algorithms to solve the problem PAPR OFDM system, this chapter details Fine describes one of the limiting, compression expansion method, constellation expansion method, selective mapping method and partial transmission Sequence method. In introducing each algorithm, for which the main problem for the corresponding improvements, so that each An algorithm have become more practical algorithms.)
