Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 105 === In this thesis, for the real packet transmission to the simulation analysis, in the receiver signal processing channel estimation, proposed an algorithm to improve the channel status information. The Regularized LS estimation method combines the known channel information from pilot signal with the channel information and the previous channel information to produce an accurate channel estimation result than the standard LS estimation method.
However, with the continuous increase in the transmission symbol, the use of preamble to produce more accurate channel information will be less and less. In the system simulation, when the channel correlation in time and LS channel estimation error, we know in the proposed method, we can according to the different SNR in the real transmission verification, get the required normalization parameter. When the packet is delivered in real, the best regularization parameters are selected according to the current environment to obtain a more accurate channel estimate for the transmission to enhance the system performance.
