Further annotation explanation is done to the present invention in conjunction with concrete application example；Fig. 6 carries for fourth embodiment of the invention
The structural schematic diagram of the filter scheduling system of confession, Fig. 7 is showing for the filter dispatching method that fifth embodiment of the invention provides
It is intended to；Fig. 8 is the structural schematic diagram that the filter that sixth embodiment of the invention provides dispatches system, and Fig. 9 is that the present invention the 7th is real
The schematic diagram of the filter dispatching method of example offer is provided；
In the embodiment shown in Fig. 6 and 7, following setting is done：It includes 3 peak-clipping modules 51 that filter, which dispatches system 5,（It cuts
Peak module 511,512 and 513, wherein peak-clipping module 512 is not shown）, CPG is not set in this 3 peak-clipping modules 51, this 3
The dispatching priority of peak-clipping module 51 reduces successively, and the peak value processing module in peak-clipping module 51 includes peak value shown in Fig. 2
Detection module, peak value window search module, peak pulse computing module and peak pulse scheduler module；In CPG scheduler modules 52
Scheduling strategy is priority scheduling strategy, and 24 CPG are provided in CPG shared resources pond 53（Fig. 6 is not shown one by one）, by Fig. 7
It is found that the filter dispatching method that the present embodiment is provided includes the following steps：
S701：Peak value processing module in each peak-clipping module checks peak value number to be treated and each peak parameters；It should
Step specifically includes：
The peak clipping threshold value of peak-clipping modules at different levels is configured, peak-clipping modules at different levels carry out peak according to every grade of respective peak clipping thresholding
Value detection carries out peak value window search according to the peak value window length of configuration, obtains respective peak point number to be treated and each peak
Value parameter；The step can specifically include following steps：
Fs/4 shift frequency modules carry out Fs/4 shift frequencies；
Frequency is fs/ 4 local oscillator can be expressed as：
fsWhen/4 up-conversion, exports and be：
n=4k:Iout=I(n) Qout=Q(n)
n=4k+1:Iout=-Q(n) Qout=I(n)
n=4k+2:Iout=-I(n) Qout=-Q(n)
n=4k+3:Iout=Q(n) Qout=-I(n)
fsWhen/4 down coversion, exports and be：
n=4k:Iout=I(n) Qout=Q(n)
n=4k+1:Iout=Q(n) Qout=-I(n)
n=4k+2:Iout=-I(n) Qout=-Q(n)
n=4k+3:Iout=-Q(n) Qout=I(n)
F is can be seen that from above-mentioned calculation formulasOnly needing to swap input data or negate when/4 shift frequency can be real
It is existing, multiplier is not needed, resource can be saved.
Peak value checks that module carries out peak value searching；It is main to realize following four function：
Amplitude and phase calculation；It is realized using Cordic arrow patterns, 8 grades of flowing structures can be met the requirements；
Four point search；First to above-mentioned output carry out 4 comparison searches, i.e., more adjacent 4 data, if preceding two
Number is different from the slope that latter two number is determining, for example one is negative slope, the other is non-negative slope, then it is assumed that peak occur
Value, then relatively intermediate 2 data, find peak value；Assuming that 4 adjacent data are respectively A, B, C and D, if A<B and C >=
D, then it is assumed that there are peak values between B and C, if B >=C, then it is assumed that B points are peak values, otherwise it is assumed that C points are peak values；
Compared with peak clipping threshold value；Then the peak value found is compared with peak clipping threshold value, is cut if peak value is more than
Peak threshold value, then it is assumed that peak value is effective, otherwise it is assumed that in vain；Whether peak value can effectively be indicated by an indication signal；
To peak amplitude processing；Finally peak amplitude is handled, i.e., subtracts peak clipping threshold value with peak amplitude, obtains
New peak amplitude；But peak phase information remains unchanged, and for non-peak point, then its amplitude is directly set as zero；Meanwhile peak
Whether value can effectively be indicated by an indication signal；
Peak value window search module carries out peak value window search, to ensure only to export a maximum value in a window length；
Adding window search is carried out to peak pulse, to ensure only to export a maximum value in a window length, due at peak
Value can influence peak clipping treatment effect when occurring than comparatively dense, in order to ensure that peak-to-average force ratio can be reduced effectively, so introducing such one
Kind binary search mechanism；The movement of sliding window has following features when adding window is searched for：After one window, to wait until again always
It is secondary just to think that next window starts, there is no peak pulse part for centre when there is peak pulse, then do not start window counting；
In a window, if current time value is also bigger than temporary maximum value, replace temporary value, and counter with current value
It resets, restarts calculation window size, is i.e. window restarts.Adding window search implementation method is described below：
First be arranged window size counter, after detecting peak value, start to window count, and using the peak value as in window most
Big peak value initial value before that is, window is not finished, encounters new peak value when window counts less than, just by the peak value and current window most
Big peak value is compared, if present peak value is big, just replaces peak-peak in window with the peak value, while restarting window counting；
Conversely, then peak-peak remains unchanged in window, window counting continues to add up；Until window terminates.Adding window search an effect be exactly
It only just can know which peak value is the largest in window at the end of window, so needing to prolong initial data when realizing
Late, it could make that peak-peak effective marker is aligned with peak-peak itself in window in this way；If first peak value is window in window
Interior peak-peak just knows peak-peak position then at the end of window, and generates maximum value effective marker, such maximum peak
Value and effective marker spacing are window length, it is possible to which it should be window length value to obtain data delay clock periodicity at least.
Peak pulse computing module obtains peak I Q data according to peak amplitude and phase information；
By the execution of step S701, respective peak value to be treated has been calculated in each peak-clipping module in the application
Several and each peak parameters（Location information including peak I Q data and peak pulse）；
