Polyphase synthesis filterbank with gr_complex input, gr_complex output and float taps.
|
pure virtual |
Gets the current channel map.
Implemented in gr::filter::pfb_synthesizer_ccf_impl.
|
static |
Build the polyphase synthesis filterbank.
numchans | (unsigned integer) Specifies the number of channels M |
taps | (vector/list of floats) The prototype filter to populate the filterbank. |
twox | (bool) use 2x oversampling or not (default is no) |
|
pure virtual |
Print all of the filterbank taps to screen.
Implemented in gr::filter::pfb_synthesizer_ccf_impl.
|
pure virtual |
Set the channel map. Channels are numbers as: N/2+1 | ... | N-1 | 0 | 1 | 2 | ... | N/2 <----------------— 0 -----------------—> freq
So input stream 0 goes to channel 0, etc. Setting a new channel map allows the user to specify where in frequency he/she wants the input stream to go. This is especially useful to avoid putting signals into the channels on the edge of the spectrum which can either wrap around (in the case of odd number of channels) and be affected by filter rolloff in the transmitter.
The map must be at least the number of streams being sent to the block. Less and the algorithm will not have enough data to properly setup the buffers. Any more channels specified will be ignored.
Implemented in gr::filter::pfb_synthesizer_ccf_impl.
|
pure virtual |
Resets the filterbank's filter taps with the new prototype filter
taps | (vector/list of floats) The prototype filter to populate the filterbank. |
Implemented in gr::filter::pfb_synthesizer_ccf_impl.
|
pure virtual |
Return a vector<vector<>> of the filterbank taps
Implemented in gr::filter::pfb_synthesizer_ccf_impl.
