gPRS源码 2008-07-14 起初的硬件有鑫旺焊回来之后缺少几个电容和1个100k的电阻，电容主要是电源处储能的功能， 100k的电阻是sim300的sim卡上的simpress管脚和VEXT之间的，没焊接时虽能找到网络，但是会出现 掉网的情况，把这些补上后，没有问题了。所以以前的经验电路还是比较准确的。电源处一定要稳定。 另外这次初始化完成后就立即发短信，第一个短信没有成功。并且在串口接收中发短信等待模块返回信息时， 返回了call ready，之后再发就可以发出去了。这应该是模块还没有准备好。Call Ready 当搜寻到网络后开始发送短信，有时会出现+CMS ERROR: 517这个错误，应该是sim卡还未准备好，所以当搜寻到网络 后需要在多等待一会。待模块发出Call Ready信号后，再操作。 2008-7-19 今天早晨在家准备调试一下这个模块发现始终找不到网络，用哪个卡都

OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.
