WIMAXsource
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. For 600MHz center frequency transceiver requirements relative velocity )
