Abstract: A speech signal is sampled (110) to form a sequence of speech data and segmented (120) into segments. The envelope of each segment is detected (210) to form an envelope segment. Each datum of the segment is divided (220) by each datum of the envelope segment to form a de-envelope segment which is transformed (230) into spectral components. Dominant frequencies are determined (310) for the spectral components with greatest magnitudes. Envelope coefficients are generated (320) by fitting a polynomial function to the segment. Phase parameters are generated (330) representing a phase of each of the dominant spectral components. The dominant frequencies, the envelope coefficients and the phase parameters are generated (340) as compressed speech data for each voiced segment. For each unvoiced segment, a carrier frequency, an amplitude and at least one sideband frequency of an amplitude modulation component are generated (430) as the compressed speech data.

Abstract: A method and system for adaptive transient fuel compensation in a cylinder of a multi-cylinder engine estimates fuel puddle dynamics for the cylinder by determining parameters of a wall-wetting model every engine cycle. Fuel delivery to the cylinder is adjusted dependent on the estimated fuel puddle dynamics. An adaptive controller (203) is characterized by three components, an adjustable compensator (207), a wall-wetting model (215), and a parameter adaptation algorithm (221). The adjustable compensator (207) receives estimates of a parameter C (223) and of a parameter bv (225) directly from the parameter adaptation algorithm (221), and adjusts fuel injected (213) dependent on the parameter estimates (223 and 225) and a desired fuel demand (205).

Abstract: Interference removal in spread spectrum signals, comprises the steps at a spread spectrum transmitter (10) of spreading information across a predetermined spectrum by phase modulating a repeating noise sequence (18), providing a spread spectrum signal and transmitting the spread spectrum signal. The method further comprises the steps at a receiver of receiving the spread spectrum signal along with interference (41) multiplying (42) the spread spectrum signal along with interference by a window function (44) providing a multiplied spread spectrum signal. The information is recovered by despreading the multiplied (48) spread spectrum signal using a reciprocal (50) of the spectrum of the repeating noise sequence to obtain a data spectrum with interference and subsequently normalize (52) to obtain a clean data spectrum. Alternatively the information can be recovered by substituting a corrupted magnitude spectrum with a prestored PN sequence magnitude spectrum (70) as shown by receiver (60).
