Description: 在通信网络中，接入技术自始至终都是发展的热点。从时分、频分、码分到目前的空分，
从TDMA、CDMA到OFDMA，从单天线到智能天线，先进的技术日新月异，层出不穷。而随着这些新
技术的涌现，WiMAX网络也逐渐成为下一代通信系统的竞争者。很多人认为WiMAX即使无法最终
取代3G，也将是构建未来4G网络的基础，因此很多国际通信设备厂商对于正在兴起的WiMAX寄予
厚望，北电网络甚至放弃了传统3G的研发而专攻WiMAX。 -In the communications network, access technology throughout the development of hot spots. From midnight, frequency division, code assigned to the current air separation, from TDMA, CDMA to OFDMA, from a single antenna to the smart antennas, advanced technology with each passing day, one after another. With the emergence of these new technologies, WiMAX network is becoming the next generation of communication systems competitors. Many people think that WiMAX if not eventually replace 3G, will also be building a foundation for future 4G networks, so many international communications equipment manufacturers who are high hopes for the emergence of WiMAX, Nortel Networks or even to abandon the traditional 3G research and development and specializing in WiMAX.

Description: 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.

Description: AGILENT关于OFDMA设计的难得的参考资料-This application note is a guide
to effective measurement and
troubleshooting of IEEE 802.16e
OFDMA “Mobile WiMAX” signals,
components, and systems. The
most distinctive term used to
describe this new technology is
OFDMA or orthogonal frequency
division multiple access, and
therefore we will use the term
OFDMA in this note as a compact
reference to the signal and its
associated standard.

Description: This book attempts to provide an overview of IP-OFDMA technology, commencing
with cellular and IP technology for the uninitiated, while endeavoring to pave
the way toward OFDMA theory and emerging technologies, such asWiMAX, LTE,
and beyond. The first half of the book ends with OFDM technology, and the second
half of the book is targeted at more advanced readers, providing research and
development-oriented outlook by introducing OFDMA and MIMO theory and endto-
end system architectures of IP- and OFDMA-based technologies.
