Title: Systems and methods for communicating desired audio information over a communications medium
Inventor: HASSAN AMER
IPC: G10L19/00
Filed: 1997-10-07
Abstract: Desired audio information intermittently present in a first audio signal is communicated over a communications medium by generating a first communications signal in the communications medium when the desired audio information is present in the first audio signal, the first communications signal representing the first audio signal encoded as blocks of communications data according to a predetermined code. A second communications signal is received from the communications medium. The received second communications signal is processed to produce processed blocks of communications data. A metric representing the validity of a plurality of the processed blocks of communications data is then determined, and a second audio signal is generated from the plurality of processed blocks of communications data when the metric is within a predetermined range. A filler audio signal such as comfort noise is generated, preferably from predetermined audio data derived from a previously received communications signal, when the metric is outside of the predetermined range. Preferably, generation of the first communications signal is discontinued when the desired audio information is absent from the audio signal, without generating an explicit discontinuity message. The discontinuous transmission function may be implemented using a separate cyclic redundancy coding (CRC) scheme, or may be implemented using a combined decoding metric derived from a forward error correction coding scheme.

Title: Method and system for determining approximate hamming distance and approximate nearest neighbors in an electronic storage device
Inventor: OSTROVSKY RAFAIL
IPC: G06F17/30
Filed: 1998-11-17
Abstract: A method and system identify in a database one or more data entries that are the nearest neighbors of a query. The database prebuilds a first set of strings by probabilistically selecting values of respective bits in each of the first set of strings based on a probability that depends on a first hamming distance. Based on the first set of strings, the database predetermines the trace values of each data entry in the database, respectively, and stores the predetermined trace values as entries in a trace table. For each trace value entry, the database identifies the data entries whose trace values are within a second hamming distance of the trace value entry, and stores the addresses of the identified data entries in the trace value entry. When the database receives a query, by identifying the trace value entry in the trace table that match the tract value of the query, the database identifies the data entries that are within the first hamming distance of the query. In addition, a method and system estimate the hamming distance between two strings in a network.
