Patent DE-19804584-A1 (DE)
Inventor: YIN LIN
IPC: H03M7/38
Filed: 1998-02-05
Abstract: A method of coding an audio electrical signal using backward adaptive prediction. A first time frame of the audio electrical signal to be coded is received and transformed into the frequency domain using a modified discrete cosine transform (MDCT). The resulting frequency spectrum has 1024 spectral components. Subsequent time frames of the audio electrical signal are then received and the MDCT is applied to each in turn so as to generate a stream of spectral data values for each spectral component. For each stream, a set of prediction coefficients is calculated for each spectral value using a predetermined number of previously received consecutive spectral values of the stream. Using the set of linear prediction coefficients, a predicted spectral value is generated and the error between the predicted spectral value and the corresponding actual spectral value calculated. The calculated errors provide a coded representation of the spectral value stream.

Title: Method of digital demodulation and synchronisation of FSK signals involves forming difference between complex values of difference phase vector and delayed complex values
Inventor: SCHEID OLIVER
IPC: H04L27/152
Filed: 1998-08-28
Abstract: The method involves converting FSK signals digitised in an ADC into complex input signals in an IQ demodulator and forming the difference phase vector of the I and Q components from which symbols are determined. The phase variation is determined from the known frequency variation of the symbols and the known sampling frequency of the ADC. The complex difference phase vector for each FSK symbol is derived from the phase variation and the complex input signal. The difference is formed between the complex values of the vector and the complex values delayed by the sampling period. The difference phase vector with minimum magnitude is derived from the complex values formed by differencing.
