STFT与WT的缺点比较明显，随着现代信号处理技术的发展，STFT与WT已经越来越不能够满足现阶段的信号处理需求，主要是很多情况下，它俩提取的信号特征太糙，不够清晰。这也导致了很多用于提高“时频分辨率”的新技术的产生，而“同步压缩小波”（SST）就是产生于这样的背景。

基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.(OFDM-based wireless broadband system simulation It contains mainly two parts, ie link-level simulator and system-level simulator.Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx .
