Description: OFDM Signal generation and decoding using QPSK as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. QAM4 and QPSK is same modulation technique. Just run the Model and with different SNRs in the Channel Block observe the performance of the OFDM. Please leave your feedback for the model so that we can improve it.

- In this paper, IEEE802.16e standard is described at first. Then an
introduction for the basic knowledge and research in MIPv6 and FMIPv6
protocol is given. A fast handover scheme of WiMAX network which
based on FMIPv6 protocol is suggested, which implements the fast
handover at IP layer associating with MAC layer at the same time.
scheme minimizes handover latency by predicting and preparing
This
the
impending handover in advance. Finally, simulation are carried out to
evaluate the performance of this fast handover scheme. The result of the
simulation shows that the fast handover scheme has good performance.

Description: OFDM仿真文档,有发射机,接收机,信道,附件有matlab仿真代码-Fixed Broadband Wireless Access (BWA) is a promising technology
which can offer high speed voice, video and data service up to the
customer end. Due to the absence of any standard specification, earlier
BWA systems were based on proprietary standard. IEEE 802.16
WirelessMAN standard specifies a Medium Access Control (MAC) layer
and a set of PHY layers to provide fixed and mobile Broadband Wireless
Access (BWA) in broad range of frequencies. The WiMAX forum has
adopted IEEE 802.16 OFDM PHY layer for the equipment manufacturer
due to its robust performance in multipath environment. The thesis
investigates the simulation performance of IEEE 802.16 OFDM PHY
layer. The Stanford University Interim (SUI) channel models are selected
for the wireless channel in the simulation. The uation was done in
simulation developed in MATLAB. Perfect channel estimation is
assumed. Platform: |
