  • Publication number: 20080239975
    Abstract: A collision handling receiver for use in a data communication network. The collision handling system and method comprises collision handling receivers together with transmitters inserting pseudo-random delays. Accordingly, multiple sources may transmit simultaneous messages to a receiver so that the messages arrive with varying signal levels and times of arrival. The receiver sorts the symbols into separate sequences by grouping together symbols having similar time of arrival. In addition, the receiver retains the sequences with sufficiently reliable symbol detection, for example, when 75% of the symbols in a sequence are detected with sufficient quality. Receiver then ranks the retained transmitters by received signal level and decodes the messages from transmitters with highest received signal level.

  • Publication number: 20080240296
    Abstract: A system and method for iterative sequential carrier acquisition for estimating and correcting large carrier frequency offsets without adding significantly to receiver complexity or preamble length. A coarse frequency estimation is performed during a brief carrier acquisition phase that is completed during a reasonably short preamble, and then the system hands frequency control to the nominal carrier frequency & phase tracking of a phase-locked loop (PLL) circuit. The present disclosure generally includes an initialization mode, a pre-lock scan mode, an iterative search mode and a termination mode.

  • Patent number: 5499288
    Abstract: The present invention describes a system and method for enabling a caller to obtain access to services via a telephone network by entering a spoken password having a plurality of digits. Preferably, the method includes the steps of: (1) prompting the caller to speak the password beginning with a first digit and ending with a last digit thereof, (2) recognizing each spoken digit of the password using a speaker-independent voice recognition algorithm, (3) following entry of the last digit of the password, determining whether the password is valid, and (4) if the password is valid, verifying the caller's identity using a voice verification algorithm.

  • Patent number: 5365574
    Abstract: A method for enabling a caller to obtain access to one or more services via a telephone network by speaking a password is described. The method begins by establishing at least one predetermined threshold value for a speaker verification signal. For each spoken character of the password, the method generates a set of parameters using a voice verification feature transformation. After entry and recognition of the password, the sets of parameters are used to generate a speaker verification signal for the password. Upon the occurrence of a predetermined call condition, the predetermined threshold value is adjusted to increase the level of security in the verification algorithm. If the signal verification signal for the password has a predetermined relationship with respect to the adjusted threshold value, the caller's identity is accepted. If not, the caller may be asked to answer certain personal questions before his or her identity is accepted.

  • Patent number: 5303299
    Abstract: The present invention describes a method for recognizing alphanumeric strings spoken over a telephone network wherein individual character recognition need not be uniformly high in order to achieve high string recognition accuracy. Preferably, the method uses a processing system having a digital processor, an interface to the telephone network, and a database for storing a predetermined set of reference alphanumeric strings. In operation, the system prompts the caller to speak the characters of a string, and characters are recognized using a speaker-independent voice recognition algorithm. The method calculates recognition distances between each spoken input character and the corresponding letter or digit in the same position within each reference alphanumeric string. After each character is spoken, captured and analyzed, each reference string distance is incremented and the process is continued, accumulating distances for each reference string, until the last character is spoken.
