【正文】 hematics sign meaning: With mean respectively the matrix or vector turn to place With grip to turn to place totally 。the ⑩ mean the K r one product。}}.II。 mean Fr ob e n us Number。 ma cal element。[month, mean the row vector k chemical element: the IN mean N rank unit matrix .Want to send out the signal matrix to carry on to all to be whole before not adopt the simplification calculate way Search, again because of the full speed rate design, P=M, as a result plications along with send out antenna And enter increment of make the number to present index number to add doubly. Our adoption and the cultural heritage 川 is similar to of the letter way model. Consider a MIMO System, have M to send out antenna, the N receives antenna, the assumption is sending out T The letter way of antenna inside the time length of the sign for flat decline(the frequency chooses not Sex)the letter way. The vector of the signal mean form is :BE receive antenna the last TXI receive signal row The quantity, the x, sends out antenna, the last TX t sends out signal row vector .Spirit. Mean From send out the falling off path that the antenna m arrives an of receive the antenna n to increase a benefit。 39。for receive Antenna .Ascend of add sex voice, can distinguish 第 38 頁 共 45 頁 model to change in to all be worth for., The square is bad for cloud, The independence of the hour distributes together of reply Gauss to change quantity random. The matrix of the signal means the form is a YXH+E, its towel X BE the IXN flatness to decline letter a way characteristic matrix The TXN adds sex voice matrix .At the matrix Y, in the X and E, the level direction mean empty Distribute, the perpendicular direction means time distribute. The S is 1= FSK39。}BE a contented real amount is hand over design of empty hour make, then send out signal The matrix satisfies Ax is a signal horoscope diagram among them .Adopt the K enters to make FSK to make, defining a FSK wave form to gather for The horoscope diagram of the ST FSK is Bee the P row vector, each chemical element in the row vector draw from Send out signal matrix Make with empty hour code of process .At each a FSK wave form sent out to send out in the signal matrix the number is a , is positive for the P x M real amount Hand over the design matrix, send out the corpse a FSK wave form in the P the time length, because of This is the full speed rate the empty hour code, each form contains a sign, the signal of ST FSKD the size of the set as TPK Al at to is hand over empty the ML of the code receive make use of BE hand over characteristic, separate the consociation ML the examination problem of several vectors thus for some Is mutually the ML examination of the independent AWGN letter way is inspire by that method, Const Pass by to deduce the separation ML signal examination method of the ST FSK 3 according to the STFSK receiver structure of the ML standard When assumption the letter way the H is to have already know, at this time of however function can such as cultural heritage Medium say. Biggest however translate the code standard i, among them k the vegetable take 1, other vegetables is draw on these ST FSK according to separate the receiver structure that the ML standard concerns with an examination, such as figure e In order to receive antenna to receive vector, the v difference Y BEN the vector constitute of receive the signal matrix, carry on to the formation we Can think matches it to receive, chasing different AN according to the above rule, the generation go acquire receive the signal matrix to resolve for the corpse independent row sigh, , to carry on the ML examination respectively all the way each time, can immediately be correspond of FSK Send out a form and send out sign to estimate a value, enter to make a conversion through K/2, get originality two Enter to make a data to flow of estimate a value a function is analytical From the type((4)with figure 2 medium can see, the wood text put forward of the examination method make ML examination mountain the consociation of several vectors examination the problem separate for the 第 39 頁 共 45 頁 The respectively examine of the quantity problem, namely to each vector Cr that has been re constructed. P The P carry on biggest however examination, we know in a send out the signal matrix FSK wave form of send out the number is a P, then receiving to carry to need to carry on a ML examination, FSK wave form can be estimate directly. Compute plications and P presents line Relate to, also be with send out antenna few Ms to present the line sexual behavior, along with send out the big line number The increment of the quantity, with concern with an examination not}I, z}and the adoption all search of concern with examination to pare, Let up 3 plexity of the receiver structures and the calculation plications consumedly, but its premise The condition is to need to know the letter way an appearance information, so need to carry on to believe an estimate of. When Separate the examination method adoption according to the best method trained a sequence[}e}carry on believing a way to estimate a value Hour, its plications will have increment, supposing at this time from send out training sign to constitute The matrix is a X, , correspond of receive the signal matrix as Yr, then estimate letter way for H=Y, take sentencing a FSK wave form as standard, parison The separation examination method and cultural heritage that this text put forward[concern with an examination and adopt not in 1,2] whole Search of concern with an examination to translate the code plications, the result From table 1 can see, be adoption all search to concern with examination it translates code the degree and cultural heritage of concern with an examination no
