- The polynomial order is n = m/2 = 5

- The polynomial F(z) (F1(z) or F2(z)) is given by
|
||||
F(w) = 2 exp(-j5w) C(x)
|
||||
where
|
||||
C(x) = T_n(x) + f(1)T_n-1(x) + ... +f(n-1)T_1(x) + f(n)/2
|
||||
and T_m(x) = cos(mw) is the mth order Chebyshev
|
||||
polynomial ( x=cos(w) )
|
||||
- C(x) for the input x is returned.

FUNCTION DESCRIPTION
|
||||
|
||||
This function computes the LSPs from the LP coefficients.
|
||||
|
||||
The sum and difference filters are computed and divided by 1+z^{-1} and
|
||||
1-z^{-1}, respectively.
|
||||
|
||||
f1[i] = a[i] + a[11-i] - f1[i-1] ; i=1,...,5
|
||||
f2[i] = a[i] - a[11-i] + f2[i-1] ; i=1,...,5
|
||||
|
||||
The roots of F1(z) and F2(z) are found using Chebyshev polynomial evaluation.
|
||||
The polynomials are evaluated at 60 points regularly spaced in the
|
||||
frequency domain. The sign change interval is subdivided 4 times to better
|
||||
track the root. The LSPs are found in the cosine domain [1,-1].
|
||||
|
||||
If less than 10 roots are found, the LSPs from the past frame are used.

INPUT AND OUTPUT DEFINITIONS
|

|

Inputs:
|
||||
L_num = 32 bit signed integer (Word32) whose value falls in the
|
||||
range : 0x0000 0000 < L_num < L_denom
|
||||
L_denom_hi = 16 bit positive normalized integer whose value falls in
|
||||
the range : 0x4000 < hi < 0x7fff
|
||||
L_denom_lo = 16 bit positive integer whose value falls in the range :
|
||||
0 < lo < 0x7fff
|
||||
|
||||
pOverflow = pointer to overflow (Flag)
|
||||
|
||||
Outputs:
|
||||
pOverflow -> 1 if the 32 bit divide operation resulted in overflow
|
||||
|
||||
Returns:
|
||||
result = 32-bit quotient of of the division of two 32 bit integers
|
||||
L_num / L_denom (Word32)

FUNCTION DESCRIPTION
|
||||
|
||||
This function is a fractional integer division of two 32 bit numbers, the
|
||||
numerator L_num and the denominator L_denom. The denominator is formed by
|
||||
combining denom_hi and denom_lo. Note that denom_hi is a normalized numbers.
|
||||
The numerator and denominator must be positive and the numerator must be
|
||||
less than the denominator.
|
||||
|
||||
The division is done as follows:
|
||||
1. Find 1/L_denom by first approximating: approx = 1 / denom_hi.
|
||||
2. 1/L_denom = approx * (2.0 - L_denom * approx ).
|
||||
3. result = L_num * (1/L_denom).

FUNCTION DESCRIPTION
|
||||
|
||||
This function produces a result which is the fractional integer division of
|
||||
var1 by var2; var1 and var2 must be positive and var2 must be greater or equal
|
||||
to var1; the result is positive (leading bit equal to 0) and truncated to 16
|
||||
bits. If var1 = var2 then div(var1,var2) = 32767.

PSEUDO-CODE
|

The original etsi reference code uses a global flag Overflow. However, in the

actual implementation a pointer to a the overflow flag is passed in.

The LSPs are quantized and transmitted at the 2nd and
|
||||
4th subframes (twice per frame) and interpolated at the
|
||||
1st and 3rd subframe.
