Embodiment 1

[0062] Embodiments of the present invention provide a FARROW decimation filter for multi-standard data, and input data of multiple formats into the FARROW decimation filter for processing, such as figure 2 As shown, the FARROW decimation filter includes: at least two input computing units 21, and each input computing unit is respectively connected to a data channel of a standard, so that subsequent data of multiple formats are processed, and each input computing unit Each unit is connected with a modulo 1 accumulator 22; the FARROW decimation filter also includes: a channel polling table 23, a channel selector 24, an input data selector 25, and an output operation matrix 26.

[0063] Among them, the input operation unit 21 is used to perform pre-extraction operation on the data to be extracted in the data channel; the modulo 1 accumulator 22 is used to perform an accumulation when the effective signal of each data to be extracted is input to the corresponding input operation u...

Embodiment 2

[0117] Embodiments of the present invention provide a FARROW interpolation filter for multi-standard data, and input data of multiple formats to the FARROW interpolation filter for processing, such as Figure 12 As shown, the FARROW interpolation filter corresponds to the channel memory 121 and the first single-input multiple-output selector 122 set for each standard data channel.

[0118] Among them, the channel memory 121 is used to store the data to be interpolated corresponding to the data channel, and the specific implementation is: after receiving a data channel containing the data to be interpolated in the data channel of at least two formats, the first single-input multiple-output selection The unit 122 outputs the data to be interpolated for each data channel in the one data channel to the corresponding channel memory.

[0119] In order to realize the interpolation of the data to be interpolated, in this embodiment, the data to be interpolated needs to be filtered fir...

Abstract

The invention discloses a filter of multi-system data and a filtering method, relating to the technical field of signal processing. The invention solves the problem of larger consumption of logic resources and higher cost of base stations. In the embodiment of the invention, the multi-system data in an extracting filter share one output operation matrix to reduce the quantity of the output operation matrix; and the multi-system data in an interpolating filter share one filtering operation unit to reduce the quantity of the filtering operation unit. The embodiment of the invention is mainly used for various digital signal processing systems.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a filter and a filtering method for multi-standard data. Background technique [0002] With the development of radio frequency, software radio and ASIC (Application Specific Integrated Circuit, application specific integrated circuit) technology, the current base station is based on a unified software radio platform and radio frequency modularization, and can combine multi-standard data through a unified middle radio frequency module , sending, receiving and separation, realizing the unification of multi-standard data on the base station hardware. In the existing base station technology, the same hardware module can be configured for multiple standards such as GSM, WCDMA, CDMA, LTE, etc., and even supports one hardware to process data of multiple standards at the same time. [0003] Since the data rates corresponding to different standard data are different, in...
