AMR-NB: LSP vectors
- q_k[i]
- the ith coefficient of the kth line spectral pair (LSP) in the cosine domain
- k
- the two lsf vectors give the LSP vectors q2, q4 at the 2nd and 4th subframes; k = 2*j
- f_j[i]
- ith coefficient of the jth LSF vector; [0,4000] Hz
- f_s
- sampling frequency in Hz (8kHz)
