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: Beyond third generation (B3G) and fourth
generation (4G) communication systems require
bandwidth efficiency and low complexity receivers to
accommodate high data rate and large number of
users per cell. This paper provides the
recommendations for why Interleave Division Multiple
Access (IDMA) stands out among all the present day
multiple access systems. Even if IDMA is a special
case of Code Division Multiple Access (CDMA), it
simply trounces CDMA as far as the cell capacity is
concerned. In IDMA, interleavers are used as the only
means for user separation. Interleaver size can be
varied for a set of users but the recommended
interleaver size is 1024bits at which it provides better
efficiency and minimum processing delay.
Investigations carried throughout this paper are while
using 1024 bit interleavers. IDMA exhibits the
tendency to handle huge number of users.

Description: Reaching Higher data rate and spectral efficiency are among the challenges expected for 4G wireless systems. Combining OFDM modulation and multiple-input multipleoutput (MIMO) help for that. In this paper, performances of a WiMAX MISO-OFDM based system are studied through
measurements done in a reverberation chamber. The used antennas’ specifications are given as well as the numerical blocks description. The results obtained are compared to a reference
case with single-input single-output (SISO) in order to evaluate the studied system’s real performances

Description: Orthogonal frequency division multiplexing (OFDM) has been proved as the dominant modulation technique for 4G communication. The use of relaying improves the BER performance of OFDM system. In this paper the BER performance of AF relaying with average power constraint (APS) is derived for an OFDM system. Also how frequency diversity scheme improves the BER performance in single antenna AF relay based OFDM system is discussed properly.
