Random-Access-for-LTE.rar - Random access preamble and algorithm designs for LTE-LTE Advanced Base Stations are clearly defined in this presentation. All definitions are based on 3GPP release 11.,2013-03-13 17:03:48,下载32次
New-Decoding-Methods-for-LDPC-Codes-on-Error-and- - This is my research about Error fixing.
For low-end devices with limited battery or computational power, low complexity decoders
are beneficial. In this research we have searched for low complexity decoder alternatives for
error and error-erasure channels. We have especially focused on low complexity error erasure
decoders, which is a topic that has not been studied by many researchers.,2013-03-13 16:29:50,下载3次
Complex_SVD_algorithm_for_Cplus.zip - To do complex SVD for non-codebook precoding in open loop spatial multiplexing in MIMO, Householder Reduction and QR Diagonalization is applied to H matrix to obtain eigenvalues and eigenvectors of matrix.

16QAM_soft_demapping.rar - This document is about 16 QAM demapping of received data. But its a soft demapping method based Log likelihood ratio(llr). So results can be used as inputs for viterbi decoder or turbo decoder. It is very usefull to decrease BER for communication systems. In addition, QPSK, 64QAM etc. demappers can be derived based on this document.,2013-03-13 15:52:49,下载73次
