scrambler.zip - Scrambler matlab file is the first block in the WiMAX physical layer chain. Scrambler which receives digital data from MAC layer randomizes the information inorder to avoid long runs of zeros and ones.,2009-09-10 18:26:35,下载26次
noise.zip - This matlab file is used to generate noise signal which is added to the transmitted signal in an AWGN channel. Based on the SNR value the power of the noise is determined.,2009-09-10 18:24:09,下载5次
Analysis_of_channel_estimation_methods_for_OFDMA. - 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.,2009-09-10 18:00:00,下载144次
