filter: adding freq_xlating_filter.
Includes QA and GRC.
Update to build_utils adds a FIR_TYPE for the type of filter and CFIR_TYPE for the type of filter where the taps are always complex (needed for freq_xlating_filter).
filter: adding IIR filter.
Include QA and GRC.
filter: copied over interpolator_taps.h to gr-filter.
filter: adding single_pole_iir_filter blocks.
QA, docs, and GRC.
filter: updating adaptive FIR filters.
No need for our own adaptive_fir class; can do everything with fir_filter.
With QA code.
filter: minor coding things.
filter: mods to fir filter bases to make consistent and simpler.
filter: improving documentation and adding GRC blocks for fir_filter_xxx blocks.
filter: adding ssc and fsf versions of filter with associated new Volk kernels.
These routines work and pass QA. They could use some performance work. the FSF is just slightly slower than before; the SCC version is more noticably slower.
Both could benefit, probably, by using SSE2 intrinsics to handle the shorts.
filter: fixed FIR filter QA code to make sure it excersizes SIMD call.
filter: added a ccf Volk dot product to use with ccf filters and used it in fir_filter_ccf.
Produces improved results to previous version.
filter: switched ccc FIR filter to use aligned VOLK calls.
filter: fff FIR filters use VOLK machine information to set alignment.
Works with SSE and AVX machines. SSE results comparable to float_dotprod still. AVX slightly faster.
filter wip and probably squash with last.
Removing unecessary d_offset counter from fir_filter.
filter: process 4 vectors each time in volk dot_prod to speed up fir filters.
This makes the volk version of the SSE FIR filter the same speed as using the hand-crafted float_dotprod from before.
filter: Fixed filter_delay and hilbert filter to work with aligned filter loads.
filter: working aligned taps loads for regular and decimating filter.
Has working QA code but needs significant performance improvements.
filter: adding ccf version for adaptive filter.
filter: wip: working on adaptive FIR filter. Moved ccc and created parent class that is not a gr_block.
filter: created polyphase_filterbank parent class to handle some initialization and setting taps of PFB blocks.
Converted pfb_channelizer_ccf over to new parent class. Passes QA.
filter: copied over pfb_channelizer to gr-filter with QA and GRC.
filter: fixed typo.
filter: added fir_filter_with_buffer to gr-filter.
Only fff and ccc versions so far. Needs work on Volk to be followed from fir_filter.
filter: added filter_delay_fc to gr-filter with QA and GRC files.
filter: some cleanup with the dc_blocker code.
filter: moved dc_blocker to gr-filter with QA and GRC blocks.
filter: added hilbert xform block with QA and GRC block.
filter: actually run the C++ unit tests.
filter: added Parks-McClellen algorithm.
Renamed gr_remez to pm_remez here. Added QA code and fixed coding style.
filter: cleanup and moving calls from gr.firdes to filter.firdes.
filter: added firdes for generating FIR filters to gr-filter.
Addes QA code in both Python and C++.
filter: added GRC block for FFT filters. Fixed example install.
filter: improved documentation for fft_filters.
filter: preparing to handle alignment better in FIR filters.
filter: fixed fft_filter tests.
filter: adding fff version of FFT filter.
filter: fixed FIR filter taps and added complex FFT filter.
filter: Reworking filter to have a set of basic implementation classes for filters of different kinds.
The GR blocks are templated now and call from fir_filters for the volk-specific implemenation.
Note the modification to build_utils.py to accomodate these changes.
filter: adding examples folder.
First example compares old filter in gr to new one in filter.
filter: fixing up fir_filter_fff to handle taps appropriately, also does decimation.
build: reworking cmake structure for include and lib directories. I think this is cleaner.
We also probably don't need the link_directories (according to the cmake guys, this is no longer necessary).
filter: work on creating gr-filter top-level component.
Builds but does not bring in libgnuradio-fft.so symbols.
