In this case, this M drives K Received signal strength processing module can drive that K transmits in processing module above for four kinds of introduced N any one.
In addition, obtain M road Received signal strength based on K road Received signal strength here, can be using this K road Received signal strength as this M road Received signal strength, also can be that this K road Received signal strength is treated to this M road Received signal strength, this application is not restricted.In specific implementation process, after driving K Received signal strength processing module 12b based on this M and obtaining M road Received signal strength, just can be transferred to external processing module by the M of this antenna data receiving port to process, or be the antenna being applied to base station end for this antenna, so this M data receiving port is then a day port for alignment base-station transmission data.
In specific implementation process, in order to the asymmetric technical problem of uplink downlink can be solved, just need by N and M arrange different, so, this this N drives the K processing module 12a and this M that transmits and drives and can only have at most one between K Received signal strength processing module 12b and provide transparent transmission function, certainly, all transparent transmission function can not provided yet.
In addition, in specific implementation process, data sending terminal or data receiver can realize transparent transmission function, so only need the conversion at one end carrying out signal, thus, decrease the quantity to the functional module that signal processes, further there is the technique effect reduced costs.
In addition, in specific implementation process, when the antenna element that this antenna submatrix 20 comprises is dual polarization a period of time, also like-polarized data input and data output situation can only be added up, such as: suppose that antenna comprises 4 antenna submatrixs 10, wherein, 4 main polarization antenna element, 4 cross polarised antenna a period of time; There are 4 main power feed networks in corresponding 4 main polarization antenna element, corresponding 4 cross polarization a period of time exist 4 cross polarization feeding networks; Wherein, riches all the way penetrates signal and is divided into four tunnels to transmit via one point of four power splitter, then sent by 4 main polarization antenna element, another road transmits and is divided into four tunnels to transmit via one point of four power splitter, is then sent by 4 cross polarised antenna a period of time; When receiving data, 4 road Received signal strength received via the 4 main polarization antenna element in tunnel and directly pass to external signal processing unit by transparent transmission function by the 4 road Received signal strength that 4 road cross polarised antenna a period of time received, in this case, the data of only adding up in a polarization send situation, namely N=1, K=4, M=4; The data of adding up in two polarised directions send situation, namely N=2, K=8, M=8.
Further, in specific implementation process, when the antenna element that this antenna submatrix 20 comprises is dual polarization a period of time, this N drives the K processing module 12a that transmits can only comprise one group, namely main polarization and cross-polarized signal is carried out merging treatment, also two groups can be comprised, namely main polarization and cross-polarized signal is carried out separately process, if and main polarization and cross-polarized signal is carried out separately process, the degree of correlation of main polarization signal and cross-polarized signals can be reduced, thus reach good polarization effect; In like manner, this M drives K Received signal strength processing module 12b can only comprise one group, and then by main polarization signal and cross-polarized signals merging treatment, also can comprise two groups, and then by main polarization signal and cross-polarized signals separately process, and then reach good polarization effect.
Further, size based on different application scenarios N and M is also different, such as: suppose that this antenna is positioned at base station side, so, because the transmitted power of the antenna of the terminal corresponding with it is less, so the receiving velocity of base station side can be caused less, in this case, in order to ensure that uplink downlink is symmetrical, just need to increase data receiving channel, namely M is greater than N; And suppose that this antenna is positioned at end side, because the data sending power of the base station of its correspondence is comparatively large, so so cause the data reception rate of end side to be greater than data transmission rate, in this case, just need to increase data transmitting channel, namely N is greater than M.Certainly, above-mentioned two situations just list two possible application scenarioss, but in specific implementation process, the corresponding relation of N and M is not limited to above-mentioned two situations.
In addition, in specific implementation process, N, dividing of size is there is no between M and K, namely N, namely N can be greater than K, also K can be less than, K can also be equaled, but as a preferred embodiment, N or M is less than K, because N road transmit to should antenna data send data channel, M is to should the data channel of data receiver of antenna, and K corresponding be the physical channel of the carrying of this antenna, if and a fairly large number of words of data channel, the increase of the manufacturing cost of antenna can be caused, thus when N or M is less than K, there is the technique effect saving antenna manufacturing cost.
