Description: WIMAX_WZ_withencoding:信道估计，相位噪声补偿，频偏估计，编解码都有
WIMAX_WZ_withoutencoding：在上面的工程基础上，去掉编解码部分
WIMAX_WZ_withoutprocessing：在上面的工程基础上，再去掉相位噪声补偿，频偏估计
WIMAX_WZ_withoutprocessing2：在上面的工程基础上，改用新的前导和导频联合信道估计方案,参考文档《基于802_16d标准的OFDM信道估计技术的研究与实现.kdh》
因为白噪声信道仿真只能体现QPSK调制和RS-CC编码的性能，需要仿真SNR可控的SUI信道，来估计信道均衡的性能。
在多普勒频偏fd>100Hz时，联合信道估计性能才比前导估计强，否则前导估计性能更优。对于600MHz中心频率，要求收发机相对运动速度大于180km/h，这种情况出现的概率不大-WIMAX_WZ_withencoding: channel estimation, phase noise compensation, frequency estimation, the codec has WIMAX_WZ_withoutencoding: the project on the basis of the above, remove the codec section WIMAX_WZ_withoutprocessing: the project on the basis of the above, then remove the phase noise compensation, offset estimation WIMAX_WZ_withoutprocessing2: In the project on the basis of the above, use the new leader and pilot joint channel estimation scheme, the document " Standards-based 802_16d OFDM channel estimation and implementation of technology .kdh" because white noise channel simulation only reflects the QPSK modulation and RS-CC coding performance requires simulation SNR controllable SUI channel, to estimate the performance of channel equalization. When Doppler shift fd> 100Hz, joint channel estimation performance was stronger than the leading estimate, otherwise better estimation performance leader.

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: |
