    Abstract: An apparatus, software modem, and method for a data communications device, such as a modem (100, 101), to determine a symbol rate and carrier frequency, from a received probe signal, for optimizing a bit rate for data transmission and reception. The various embodiments utilizing a processor (108) or a digital signal processor (106) receive a probe signal, which also typically contains noise and other distortions, particularly envelope delay distortion. The various method and apparatus embodiments then determine a variance of the envelope delay distortion, either directly or indirectly as a correlate of attenuation distortion or as a correlate of a selected transmit pre-emphasis filter specified under the ITU V.34 protocol. The variance of the envelope delay distortion is then utilized to eliminate or disable certain symbol rates and corresponding carrier frequencies in the determination of an optimal symbol rate and carrier frequency for data transmission and reception.

    Abstract: A radio receiver (700) uses automatic frequency control for locking a controlled reference signal (108) to a pilot reference signal (114) that has been distorted by multipath fading. The radio receiver (700) is programmed to sample the pilot reference signal (114) over a predetermined time interval to determine an average pilot frequency, and applies a first weighting function to the average pilot frequency to generate a weighted pilot frequency and a second weighting function to a controlled frequency of the controlled reference signal (108) to generate a weighted controlled frequency. The radio receiver (700) sums the weighted pilot frequency with the weighted controlled frequency to provide an update frequency, and modifies the controlled reference signal (108) such that its frequency matches the update frequency. The radio receiver (700) continues these programmed steps so as to lock the controlled reference signal (108) to the pilot reference signal (114).

    Abstract: A method and apparatus is used for securing programming information in communication device (100). The apparatus comprises a read-only memory (116) containing a current serial number normally expected to be unchanged from an original serial number pre-programmed into the read-only memory (116), the original serial number being unique to the communication device (100).

    Abstract: A tonal sound recognizer determines tones in a tonal language without the use of voicing recognizers or peak picking rules. The tonal sound recognizer computes feature vectors for a number of segments of a sampled tonal sound signal in a feature vector computing device (120), compares the feature vectors of a first of the segments with the feature vectors of another segment in a cross-correlator (130) to determine a trend of a movement of a tone of the sampled tonal sound signal, and uses the trend as an input to a word recognizer (140) to determine a word or part of a word of the sampled tonal sound signal.
