Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution % % compute the forward/backward Campbell/specgtrogram % % INPUT: % y (n x 2) each column is measured from a different sensor % /////// % __ % |s1| y(:,1) % |__| % __ % / \ ________|/ % | | | s2 |/ y(:,2) % \____/ --------|/ % % Fs Sampling frequnecy % % OUTPUT: % B spectrogram/Campbel diagram % x x-axis coordinate vector (time or Speed) % y y-axis coordinate vector (frequency [Hz])

The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequences include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric. Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.

這是06年4月剛剛完成的程序,從opencore.org下載而來。用vhdl語言描寫,以及matlab仿真,testbench,以及在xinlinx上的綜合。 The MDCT core is two dimensional discrete cosine transform implementation designed for use in compression systems like JPEG. Architecture is based on parallel distributed arithmetic with butterfly computation.

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)

用匯編語言做的一個打字游戲。運行環境是MASN5.0。 1,用戶打開軟件時先出現歡迎界面,當用戶輸入字符’1’時,再進入打字界面 當用戶按的是”ESC”鍵時,退出打字游戲 當用戶輸入不是數字”1”或者不是按的”ESC”鍵時,屏幕不動作,直到用戶輸入數字”1”或者按的”ESC”鍵時 2,打字字符從第二行開始顯示(雙數行為顯示打字內容,單數行由用戶輸入) 打字內容:1), We will see his boat and then.We ll say goodbye to him. 2), He ll be away for two months.We are very proud of him. 3,用戶輸入的和上一行相對應相等時,表示輸入正確,否則輸入錯誤,則顯示’#’ 當用戶按下”ESC”鍵,退出打字程序 4,顯示用戶打字的正確性,假如錯誤數小于10字符,顯示” Very Good!” 否則顯示” Very Bad!” 5,當用戶輸入一次時,假如用戶還想重新打字游戲,請按數字鍵”3”,否則按”ESC”鍵退出打字程序
