VISA是标准化的I/O函数库及其相关范围的总称。作为通用的I/O标准，VISA是面向器件而不是面向接口总线的。因此VISA与其它现有的I/O接口软件相比，最大的优点就在于它与硬件接口无关，是一个标准且独立于硬件设备、接口、操作系统和编程语言的I/O函数库，可以说它是现有I/O接口软件的一个超集。

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.
