LSPs have several properties (like 52 less sensitivity to quantisation noise) that make them superior to 53 direct quantisation of {ak}. 54 55 A(z) is a polynomial of order lpcrdr with {ak} as the coefficients. 56 57 A(z) is transformed to P(z) and Q(z) (using a substitution and some 58 algebra), to obtain something like: 59 60 A(z) = 0.5[P(z)(z+z^-1) + Q(z)(z-z^-1)] (1) 61 62 As you can imagine A(z) has complex zeros all over the z-plane. P(z) 63 and Q(z) have the very neat property of only having zeros _on_ the 64 unit circle. So to find them we take a test point z=exp(jw) and 65 evaluate P (exp(jw)) and Q(exp(jw)) using a grid of points between 0 66 and pi. 67 68 The zeros (roots) of P(z) also happen to alternate, which is why we 69 swap coefficients as we find roots. So the process of finding the 70 LSP frequencies is basically finding the roots of 5th order 71 polynomials. 72 73 The root so P(z) and Q(z) occur in symmetrical pairs at +/-w, hence 74 the name Line Spectrum Pairs (LSPs). 75 76 To convert back to ak we just evaluate (1), "clocking" an impulse 77 thru it lpcrdr times gives us the impulse response of A(z) which is 78 {ak}. 79 80 \*---------------------------------------------------------------------------*/ 81 47 82 #ifdef HAVE_CONFIG_H 48 83 #include "config.h" … … 64 99 #ifdef FIXED_POINT 65 100 66 67 68 101 #define FREQ_SCALE 16384 69 102 … … 73 106 /*#define X2ANGLE(x) (acos(.00006103515625*(x))*LSP_SCALING)*/ 74 107 #define X2ANGLE(x) (spx_acos(x)) 108 109 #ifdef BFIN_ASM 110 #include "lsp_bfin.h" 111 #endif 75 112 76 113 #else … … 89 126 /*---------------------------------------------------------------------------*\ 90 127 91 92 93 94 95 96 128 FUNCTION....: cheb_poly_eva() 129 130 AUTHOR......: David Rowe 131 DATE CREATED: 24/2/93 132 133 This function evaluates a series of Chebyshev polynomials 97 134 98 135 \*---------------------------------------------------------------------------*/ … … 100 137 #ifdef FIXED_POINT 101 138 102 static inline spx_word32_t cheb_poly_eva(spx_word32_t *coef,spx_word16_t x,int m,char *stack) 103 /* float coef[] coefficients of the polynomial to be evaluated */ 104 /* float x the point where polynomial is to be evaluated */ 105 /* int m order of the polynomial */ 139 #ifndef OVERRIDE_CHEB_POLY_EVA 140 static inline spx_word32_t cheb_poly_eva( 141 spx_word16_t *coef, /* P or Q coefs in Q13 format */ 142 spx_word16_t x, /* cos of freq (-1.0 to 1.0) in Q14 format */ 143 int m, /* LPC order/2 */ 144 char *stack 145 ) 106 146 { 107 147 int i;
