语音识别基于hmm(隐马尔可夫模型)算法代码汇总(算法源码及应用)

正交频分复用（OFDM，Orthogonal Frequency Division Multiplexing）技术可以出色的对抗抗多径衰落、消除码间干扰且具有极高的频谱利用率。此外它还采用了快速傅立叶变换，大大降低了收发机的实现复杂度，因此被广泛地应用于HDSL、ADSL、DAB、HDTV、WLAN等领域中。但是，目前OFDM技术还有很多关键问题没有得到有效解决，如对频偏敏感、高峰均功率比问题等，这些都限制了OFDM技术的近一步广泛应用。本论文主要围绕自适应压扩法降低峰均功率比问题展开论述，并利用matlab软件完成了仿真。主要做了以下工作：论文首先回顾OFDM发展历程，说明了该技术的优缺
