discrete symbol
解釋
專用符號-
In the synchronous techniques based pilot symbols, here propose a frequency offset estimating arithmetic using discrete pilot symbols. we pick up integer times sub - carrier frequency offset from the same ofdm symbol and estimate exact
此外,在頻偏估計方面,推導出短訓練序列前後兩段時域符號間的關系,並利用此進行粗頻偏估計,使頻率偏移的估計范圍大大增加。 -
Secondly, a dstft ( discrete short time fourier transform ) - based demodulation method for the 2fsk signal is studied and algorithms for symbol synchronization and symbol decision are analysed
重點研究了基於離散短時傅里葉變換解調2fsk信號的方法,分析了幾種碼元同步演算法和碼元判決演算法。 -
And also the paper researches on the two - dimensional pilot - symbol - aided channel estimation, analyzes and realizes the methods that one is realized by the discrete shift - variant 2 - d wiener filter, and the other is realized by the two cascaded orthogonal 1 - d wiener filter
分析了時頻二維通道估計方法和兩個級聯的一維通道估計方法,並對這兩種方法加以實現,最後給出了相應的實驗結果。
