Abstract:
A method of encoding quantized frequency represented data, the data comprising zero and non-zero data, the method comprising:for zero data: determining a zero run length (n); determining a Golomb parameter (m) as a function of the zero run length, wherein the Golomb parameter (m) is determined using the equation m=&boxdr;log2n&boxdl;; encoding a quotient (Q) as a function of the zero run length and the Golomb parameter; encoding a remainder (R) as a function of the zero run length, the Golomb parameter, and the quotient; and concatenating the coded quotient and coded remainder; and for non-zero data: encoding the nonzero data as a function of a value of the non-zero data and a sign of the non-zero data.
