The detection and parameter estimation based on high - order statistics are another approach for ds - ss / bpsk signals. in this paper, a sort of detectors based on fourth - order statistics slices are presented to detect the presence of signal and estimate the carrier frequency and symbol period of ds - ss / bpsk signal
高階統計分析技術是檢測直接序列擴頻信號的另一途徑，本文提出了一類基於和四階統計量切片的ds - ss / bpsk信號的檢測與參數估計方法。 -
The on the stage placed a wood, having on the wood two slices of is tieupped tight glass by the rubber bands. ask the audience draws out a card, and put to go into the whole card to wash. the magician shots into the whole card glass, only the card that the audience choose runs to two pieces of glass middles unexpectedly. very exciting satge magic. the video frequency plays to show
臺上放置了一個木架，木架上有兩片被橡皮筋捆緊的玻璃.請觀眾抽出一張牌，並放入整副牌中洗一洗.魔術師將整副牌射向玻璃，唯獨觀眾所選的牌竟然跑到兩塊玻璃中間 -
Using this system, we have studied matrine - inhibittory effect and trifluoperation - neuroprotection effect in hippocampal slices, also discussed the mechanism of long - term potentiation using anesthetic rats. the experiment results showed that matrine can inhibit the hyperactivity induced by penicillin sodium in dosage by changing the relative parameters of field potential ; trifluoperation can alter ps change with the time, enhance the degree and the ratio of ps recovery, then minis the hypoxic injury ; high frequency stimulate can increase ps amplitude and epsp slope for long time, buildup the in / out function of nerve cells, and enhance synaptic plasticity
結果表明，苦參堿能夠劑量依賴性地抑制青霉素誘導的神經元順向信號傳導激活過程，使細胞外記錄到的場電位各個參數發生相應改變；三氟拉嗪可以改變ps的時相變化，提高ps的恢復程度和恢復率，減小了神經元因缺氧引起的不可逆損傷；高頻刺激（ highfrequencystimulate ， hfs ）可以長時間的增強ps的幅度和epsp的斜率，進而增強神經元的輸入輸出功能，增加了突觸的可塑性。
