The method flow that the embodiment of the invention one provides referring to Fig. 4, comprising:

Step 41, two terminal MS 1 and MS2 adopt respectively the STTD pattern-coding, and data are modulated after will encoding again, form the transmitter code matrix.

Wherein, have one group of initial data to enter the STTD encoder in step 41 in the terminal MS 1, the transmitter code matrix that the data after will encoding are again modulated formation is $S=\left[\begin{array}{cc}{s}_1& {\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& -{\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\end{array}\right].$ One group of initial data enters the STTD encoder among the MS2 among the MS2, and the data after will encoding are again modulated and formed the transmitter code matrix $P=\left[\begin{array}{cc}{s}_3& -s_4^{*}\\ s_4& s_3^{*}\end{array}\right].$ So the transmitter code matrix that two terminals form is following form: $\mathrm{Matrix}\_A=\left[\begin{array}{c}S\\ P\end{array}\right],$ Namely $\mathrm{matrix}\_A=\left[\begin{array}{cc}{s}_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\\ s_3& -s_4^{*}\\ s_4& s_3^{*}\end{array}\right].$ For the ease of understanding, MS1 and transmitter code matrix S and P that MS2 forms are separate, S and P are combined to form Matrix_A herein and are for convenient understanding on first and second running time-frequency resource, the transmitter code matrix that MS1 and MS2 launch has respectively formed Matrix_A.

Step 42, with the emission matrix of step 41 gained $\mathrm{matrix}\_A=\left[\begin{array}{cc}{s}_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\\ s_3& -s_4^{*}\\ s_4& s_3^{*}\end{array}\right],$ Launch at first and second running time-frequency resource respectively via two antennas among two antennas among the MS1 and the MS2.Wherein, the antenna among the MS1 is first and second row data of emission matrix respectively, and the antenna among the MS2 is third and fourth row data of emission matrix respectively.

Step 43, one group of initial data among the MS1 described in the step 41 is entered STTD encoder among the MS1 again, the data behind the coding are modulated form the transmitter code matrix $S=\left[\begin{array}{cc}{s}_1& {\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& -{\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\end{array}\right].$ Described in the step 41 among the MS2 one group of initial data again enter in the STTD encoder among the MS2, the transmitter code matrix that Data Modulation behind the coding forms is done the preliminary treatment conversion, preliminary treatment herein is transformed to gets negative conversion, namely each data symbol in the transmitter code matrix is got negatively, formed the transmitter code matrix

$-P=\left[\begin{array}{cc}-s_3& s_4^{*}\\ -s_4& -s_3^{*}\end{array}\right].$

Getting negative conversion described in the above step 43 not just is confined to mentioned above initial data among the MS2 be entered STTD encoder among the MS2, the emission matrix that data behind the coding are modulated formation is done and is got negative conversion, also can be that the initial data among the MS1 is entered in the STTD encoder among the MS1, the emission matrix that data behind the coding are modulated formation is done and is got negative conversion, namely each data symbol in the transmitter code matrix is done and got negative conversion, so, form the transmitter code matrix at third and fourth running time-frequency resource

$-S=\left[\begin{array}{cc}-s_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ -s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\end{array}\right].$

Wherein, according to above-mentioned description to step 43, what can obtain that MS1 and MS2 common combination form obtains the transmitter code matrix $\mathrm{Matrix}\_B=\left[\begin{array}{c}S\\ -P\end{array}\right]$ Or $\mathrm{Matrix}\_B=\left[\begin{array}{c}-S\\ P\end{array}\right].$ Describe as an example of following matrix example in the present embodiment, adopt $\mathrm{Matrix}\_B=\left[\begin{array}{c}S\\ -P\end{array}\right],$ Namely $\mathrm{matrix}\_B=\left[\begin{array}{cc}{s}_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\\ {-s}_3& s_4^{*}\\ -s_4& {-s}_3^{*}\end{array}\right].$

Step 44, with MS1 and MS2 with formed transmitter code matrix $\mathrm{Matrix}\_B=\left[\begin{array}{c}S\\ -P\end{array}\right]$ On third and fourth running time-frequency resource, go out by four antenna transmissions.

Be convenient to understand, step 44 is the transmitter code matrixes with MS1 and MS2 formation $\mathrm{matrix}\_B=\left[\begin{array}{cc}{s}_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\\ {-s}_3& s_4^{*}\\ -s_4& {-s}_3^{*}\end{array}\right]$ Go out by antenna transmission.Detailed process is: on third and fourth running time-frequency resource, the antenna among the MS1 is first and second row data symbol of emission matrix respectively, and the antenna among the MS2 is third and fourth row data symbol of emission matrix respectively.

Above-described embodiment is to be the explanation of the diversity transmission pattern of 1 uplink multi-users virtual MIMO to Rate, below embodiment two be that to adopt Rate be the diversity transmission pattern of 2 uplink multi-users virtual MIMO.For the ease of understanding embodiment two, in embodiment two, MS1 is not identical in the initial data of priority twice emitting with MS2, can think that also MS1 and MS2 are not the data that first and second running time-frequency resource of repeat its transmission is launched on third and fourth running time-frequency resource, but launch new data, therefore, embodiment two is that a kind of Rate is 2 launching technique.

Embodiment three, a kind of ascending transmission method.Adopting in the present embodiment Rate is 2 diversity mode.Still adopt the network construction form among the embodiment one.Below in conjunction with accompanying drawing 6, the method that the present embodiment is provided describes, and comprising:

Step 61, form separately transmitter code matrix at two user MS1 and MS2.Wherein, one group of initial data enters the STTD encoder among the MS1 among the MS1, and the Data Modulation behind the coding is formed the transmitter code matrix $S_{}$ ${}_1=\left[\begin{array}{cc}{s}_1& -{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_2^{*}\\ s_2& {\mathrm{<figure-callout\; id="1"\; label="s"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">s</figure-callout>}}_1^{*}\end{array}\right].$ One group of initial data enters the STTD encoder among the MS2 among the MS2, and the Data Modulation behind the coding is formed the transmitter code matrix $P_{}$ ${}_2=\left[\begin{array}{cc}{p}_1& -{\mathrm{<figure-callout\; id="2"\; label="p"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">p</figure-callout>}}_2^{*}\\ p_2& {\mathrm{<figure-callout\; id="1"\; label="p"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">p</figure-callout>}}_1^{*}\end{array}\right],$ So first and second running time-frequency resource

Upper transmitter code matrix is following form:

Step 62, with the transmitter code matrix of step 61 gained, launch at first and second running time-frequency resource via two antennas among two antennas among the MS1 and the MS2.Wherein, the antenna among the MS1 is first and second row data symbol of emission matrix respectively, and the antenna among the MS2 is third and fourth row data symbol of emission matrix respectively.

Another group of different and the initial data described in the step 61 enter the STTD encoder among the MS1 among step 63, the MS1, and the Data Modulation behind the coding is formed the transmitter code matrix $S_{}$ ${}_2=\left[\begin{array}{cc}{s}_3& -s_4^{*}\\ s_4& s_3^{*}\end{array}\right];$ Another group of different and the initial data described in the step 61 enter the STTD encoder among the MS2 among the MS2, and the Data Modulation behind the coding is formed the transmitter code matrix $P_{}$ ${}_2=\left[\begin{array}{cc}{p}_3& -p_4^{*}\\ p_4& p_3^{*}\end{array}\right],$ To the emission matrix that forms in the STTD encoder $P_{}$ ${}_2=\left[\begin{array}{cc}{p}_3& -p_4^{*}\\ p_4& p_3^{*}\end{array}\right]$ The preliminary treatment conversion, namely the secondary series data symbol of transmitter code matrix is done and is got negative conversion, form the transmitter code matrix $P_{}^{}$ ${}_2^{,}=\left[\begin{array}{cc}{p}_3& p_4^{*}\\ p_4& -p_3^{*}\end{array}\right].$

Can draw according to content illustrated in the step 63, on third and fourth running time-frequency resource, the transmitter code matrix that is made of MS1 and MS2 is $\mathrm{matrix}\_B=\left[\begin{array}{cc}{s}_3& -s_4^{*}\\ s_4& s_3^{*}\\ p_3& p_4^{*}\\ p_4& {-p}_3^{*}\end{array}\right]=\left[\begin{array}{c}{S}_2\\ {\mathrm{<figure-callout\; id="2"\; label="P"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">P</figure-callout>}}_2^{\&prime;}\end{array}\right].$ Similarly, the preliminary treatment object in the step 63 also can be the transmitter code matrix $S_{}$ ${}_2=\left[\begin{array}{cc}{s}_3& -s_4^{*}\\ s_4& s_3^{*}\end{array}\right],$ Transmitter code matrix after the preliminary treatment conversion is ${\mathrm{<figure-callout\; id="2"\; label="S"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">S</figure-callout>}}_2^{\&prime;}=\left[\begin{array}{cc}{s}_3& s_4^{*}\\ s_4& -s_3^{*}\end{array}\right],$ Then there are MS1 and MS2 at the transmitter code matrix that third and fourth running time-frequency resource forms to be $\mathrm{matrix}\_B=\left[\begin{array}{cc}{s}_3& s_4^{*}\\ s_4& {-s}_3^{*}\\ p_3& -p_4^{*}\\ p_4& p_3^{*}\end{array}\right]=\left[\begin{array}{c}{\mathrm{<figure-callout\; id="2"\; label="S"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">S</figure-callout>}}_2^{\&prime;}\\ {\mathrm{<figure-callout\; id="2"\; label="P"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">P</figure-callout>}}_2\end{array}\right].$ The result who adopts these two kinds of ways in the end to obtain in step 63 is identical.

Step 64, MS1 and MS2 are with the transmitter code matrix that forms $\mathrm{Matrix}\_B=\left[\begin{array}{c}{S}_2\\ {\mathrm{<figure-callout\; id="2"\; label="P"\; filenames="S2008100402786E00021.png"\; state="\{\{state\}\}">P</figure-callout>}}_2^{,}\end{array}\right]$ On third and fourth running time-frequency resource, go out by four antenna transmissions.
