Channelization
- channelize — Channelization: frequency multiplexing of m input signals into a single signal (but with bandwidth multiplied by m)
- downconvert_init — Initialization of a baseband down-converter.
- downconvert_process — Down-conversion to baseband.
- iqi_blind_est — I/Q imbalance blind estimation
- iqi_cor — I/Q imbalance correction
- iqi_irr — Compute Image Rejection Ratio (IRR), given the gain and phase imbalance of a quadrature mixer
- polyphase_decimation — Apply a FIR filter and decimate the output, using an efficient polyphase structure
- polyphase_filter — Creation of a polyphase decimation filter structure
- polyphase_form — Creation of the polyphase representation of a signal
- unchannelize — Extract m channels (with identical bandwidth) using a polyphase filter bank and FFT (Harris method).
