Abstract: The speech is sampled in such a way as to obtain successive voice frames each including a predetermined number of samples, and with each voice frame are determined parameters of a code-excited linear prediction model. The parameters include a long-term excitation digital word vi extracted from an adaptive coded directory LTD, and an associated long-term gain Ga, as well as a short-term excitation word cj extracted from a fixed coded directory STD and an associated short-term gain Gc. The product of the long-term excitation extracted word times the associated long-term gain is summed SM with the product of the short-term excitation extracted word times the associated short-term gain. The summed digital word is filtered in a low-pass filter FLCT having a cutoff frequency greater than a quarter of the sampling frequency and less than a half of the latter, and the adaptive coded directory is updated with the filtered word.

Abstract: A cellular telephone includes a plurality of power amplifiers having a common operating region. If one of the amplifiers has to be deselected, a desired moment for the switching to another amplifier is defined based upon a predetermined transmission interrupt criterion. The power continues to be adjusted with the currently selected amplifier until the instant of switch over. Switching to the other amplifier may then be performed after the transmission has been interrupted.

Abstract: A device includes a receiver including an estimation block for estimating the impulse response of the transmission channel and a transformation block. The transformation block may include a preprocessing block for determining a phase minimum transformed impulse response corresponding to a transformed channel based upon the estimated impulse response of the transmission channel, and a filter for filtering the signal received. This makes it possible to retain equality between the autocorrelation of the signal received and the autocorrelation of the filtered signal. Further, the receiver may include an equalizer for applying an equalization processing operation to the filtered signal while taking account of the transformed impulse response.

Abstract: A method and apparatus for performing head switch operations in a magnetic disk system having a magnetic disk device that is segmented into a plurality of cylinders, which cylinders are grouped into an inner zone, a middle zone, and an outer zone. The inner zone is near the innermost area of the magnetic disk device. The outer zone is near the outermost area of the magnetic disk device. The middle zone is in between the inner zone and the outer zone. The head switch is performed from a current head to a target head. Prior to the head switch, the system determines if the current cylinder is in either the inner zone or the outer zone. When the current cylinder is in either the inner zone or the outer zone, the system seeks the current head to the middle zone, whereupon the system performs a head switch from the current head to the target head. When the current cylinder is not found to be in either the inner zone or the outer zone, i.e. when the current cylinder is in the middle zone, then the system performs the head switch from the current head to the target head without first performing a seek. After either of the above described head switch operations, the system seeks the target head to the target cylinder, when necessary.

Abstract: The present invention provides an improved disc drive. In one embodiment of the present invention a disc drive capable of spinning a disc, which contains more than one type of data is disclosed. A first type of data is associated with a first speed, and a second type of data is associated with a second speed that is faster than the first speed. The disc drive includes a drive mechanism, which may spin the compact disc at the first and second speeds and retrieve data from the compact disc at either speed. The disc drive also includes an elastic buffer, which is in communication with the drive mechanism. The buffer receives data from the drive mechanism at a variable input data rate and outputs data at a variable output data rate. Whereby when the drive mechanism spins the compact disc at the second speed the buffer may receive the first type of data without causing the drive mechanism to slow down to the first speed, and the buffer may output the first type of data at the variable output data rate. Preferably, the variable output data rate is a first data rate that is associated with the first format.

Abstract: A disk resident system for managing defective data sector information in a defective data sector map in a headerless format magnetic disk device. The defective data sector map is stored in gaps between fields in the headerless disk format itself or in existing disk administration fields. The defective data sector map includes a plurality of binary digits that individually correspond to a defective or non-defective status of an individual data sector on at least one section of at least one track proximate to the defective data sector map. The defective data sector map can be minimized by compressing repetitive 0's or 1's in the map. ECC coding and/or other redundancy checks can be included to ensure validity of the defective data sector map.

Abstract: A disk resident system for managing split data sector information in a headerless format magnetic disk device. The split data sector information is stored in a split data sector information field that is recorded in available areas within a headerless disk format such as the gaps within the headerless disk format or in available space within disk administration fields. Preferred areas within a headerless disk format include the gap immediate preceding a servo burst, the gap immediately following a servo burst, or within the servo burst itself, so that the split data sector information is readily available at the time the servo burst is read and interpreted. Information in a split data sector information field can include various combinations of the number of bytes in a split data sector segment that follows a first servo burst, the number of fixed length full data sectors between the first servo burst and an adjacent second servo burst, and the number of bytes in a split data sector segment that follows the second servo burst. Any split data sector information not expressly represented in a split data sector information field can be calculated because the number of bytes between a pair of adjacent servo bursts is known. Overlapping split data sector information in successive split data sector information fields can be used for look-ahead purposes or data integrity purposes. A split data sector information field can also be accompanied by an ECC type field for data integrity check purposes.
