Integrating trellis-coded modulation with threaded algebraic space–time block code, trellis-coded modulation space-time block code is presented, which has the advantage of full-diversity and small detection delay. Based on TCM pre-processing, the minimum distance between different codeword matrixes of the TCMST block code is maximized, so the average bit error rate of the TCMST block code is lower than that of the TAST block code at the same signal noise ratio.

TCMST分組碼具有滿發(fā)送分集度和檢測延遲小等優(yōu)點；由于采用了TCM預(yù)處理黄片免费视频高清在线观看，使得不同TCMST分組碼碼字矩陣間的最小距離達(dá)到了最大化，因此在相同信噪比情況下，TCMST分組碼具有比TAST分組碼更低的平均誤比特率www.狼友视频网站。

This paper proposed to use elliptical Gabor filter with least redundancy to convolute with palmprint,sub-bands with 4 scales and 6 directions are obtained,calculate the average and deviation of every sub-band,48D texture feature is extracted,and normalize the 48D feature in the whole database,finally use distance of absolute value to measure the difference between two feature vector.The result shows the arithmetic proposed by this paper has a little high retrieval accuracy.
