Besides, several contrast enhancing approaches were compared in the thesis, including histogram equalization, homo - filters, and wavelet transform. an algorithm based on the polygon approximation is developed
本論文對比了現有的一些圖像對比度提高的方法，包括直方圖均衡化、同態濾波器和小波同態濾波法在水下圖像對比度增強中應用的效果。 -
Frequency - domain equalization. at the same time discusses some key problems in ofdm : high ratio of peak - to - average power of output signals, problem of synchronization, channel estimation, adaptive bit, power and subcarrier allocation. emphasize on channel estimation, and present a new algorithm which can filtering more interpolation errors and noise. for the sake of improve the performance of resist narrowband noise and make efficient use of the spectrum apply malvar wavelet division
同時就ofdm系統中的一些關鍵問題如峰值平均功率比（ papr ）太高，同步問題，通道估計，通道、比特與功率必須動態分配進行了研究，著重研究了通道估計問題並提出一種改進的方法，能濾除更多的噪聲分量和插值誤差，提高系統的性能；為了提高抗窄帶噪聲的性能和提高通道利用率，用malvar小波變換實現了不等帶寬分配。
